Product defects are not uncommon but an organization must act quickly to eliminate them. This will ensure customers have a good experience and the brand doesn’t suffer. In the event of a complaint, an organization can rely on the analysis of an 8D report sample to address errors and improve quality.

The 8D methodology is a structured and systematic approach to problem-solving. From an 8D problem-solving example it’s clear that it not only identifies a problem but also recognizes the weaknesses in the system. Analysis of an 8D report example prevents future occurrences of similar issues.

Examples Of 8D Reports

8d problem-solving report example, 8d problem-solving example.

An 8D problem-solving example shows the strength of this model lies in its methodology, structure and discipline. Organizations can effectively use an 8D report example to analyze defects, its root causes and ways to implement corrective actions.

Let’s have a look at these 8D reports.  

An organization had a problem with holes appearing in its metal cast toy parts. They found that about 3% of their last batch received complaints after operations due to pin-hole defects. An analysis was submitted after the purchase head asked for a full 8D report example . Here’s a look at the 8D report sample that was submitted.

D1 : Names of team members, team leader and manager.

D2 : The problem reported by the customer is described by answering the following questions:

• What is the problem? A pin-hole defect
• Who reported it? Tulip Pvt Ltd
• When did it occur? Seen in the last batch
• Why did it happen? Due to a defect in the casting base
• How much production is affected? 3% of the products are defective.

  These questions aim to simplify their approach to problem-solving.

D3 : Once the problem is defined, the defective parts are segregated.

D4 : The root cause of the problem is identified by answering the following questions:

• Why is there a pin-hole defect?
• Why are core problems arising?
• Why wasn’t the core cured properly?
• Why was drying/curing time not modified?

These questions reveal that curing time was not validated and that was the root cause of the problem.  

D5 : A permanent corrective plan is recommended to the quality assurance engineer. It is proposed that product and process should be validated for new drying time.

D6 : Permanent corrective actions are implemented. 10 samples are collected. Product and process characteristics of each sample are checked.

D7 : Preventive measures are recommended to ensure the problem doesn’t recur.

D8 : Team and individual contributions are recognized by the manager. The team leader and team members are rewarded for their efforts.  

An organization received customer complaints about shrinkage on an automobile part. The management demanded a thorough analysis based on an 8D problem-solving example . Here’s the 8D report sample that was submitted:

D1 : A team is created with supply team members, team leader and manager.

D2 : A customer complaint is used to describe the problem. The problem is established by answering the following questions:

• What is the complaint? Shrinkage on sump.
• When was it seen? In the last batch.
• Why did it happen? Due to a defect in the entrance area.
• Who reported the problem? Albert D’Souza
• How much production is affected? Nearly 2%

These questions allow the team to devise a containment plan.  

D3 : As a containment action the team decides to stop consignments and segregate the good parts immediately.

D4 : To identify the root cause, the team has to answer the questions defining the problem. They are:

• Why was there a shrinkage at the ingate area?
• Why were high pouring temperatures used?
• Why was the pyrometer reading incorrect?
• Why was the pyrometer condition not checked?

The root cause of the problem is revealed to be a faulty pyrometer.

D5 : As a permanent corrective plan, periodic checking of the pyrometer is suggested to the maintenance supervisor.

D6 : Permanent corrective action is implemented and pyrometers are scheduled for weekly checks.

D7 : Periodic checking and proper maintenance of pyrometers are factors to prevent a recurrence.

D8 : The team effort is recognized. The manager and team are praised for solving the problem.

An 8D report example will show that Root Cause Analysis (RCA) is an integral part of the 8D process. It helps managers establish problem statements, identify potential causes, compare theories and confirm the main cause of a problem. You can establish the root cause in an 8D report example by asking the most relevant questions related to the defect.

8D Report and template

8D Report: this article explains the 8D Report in a practical way. Besides the explanation of what this concept is, we also the 8 disciplines and the importance of teamwork. Next to that we also provide a template to get strated. Enjoy reading!

What is an 8D Report? The meaning

The 8D Report or 8d corrective action report is a problem-solving approach for product and process improvement. Furthermore, 8D Methodology is used to implement structural long-term solutions to prevent recurring problems. The 8D Report was first used in the automotive industry.

During World War II the 8D Method was used in Team Oriented Problem Solving (TOPS) in the United States under Military Standard 1520. It was later used and popularized by car manufacturer Ford .

In the 1990s Ford continued to develop the 8D process as a result of which the process is said to have found its origin in the automotive industry. Today, the 8D Method can be used to write formal reports and it can be applied as a working and thinking method for smaller problems.

The 8D Report is also used as a means of communication within companies, which makes the problem solving method transparent and can therefore be applied to the entire production chain. The 8D method is also known as: Global 8D , Ford 8D or TOPS 8D .

8D Report: eight disciplines

The 8D Methodology mainly focuses on solving problems and comprises 8 steps or disciplines. It helps quality control staff find the root cause of problems within a production process in a structured manner so that they can resolve the problem(s).

In addition, it helps implement product or process improvements, which can prevent problems. The 8D Report is about mobilizing a good team that has sufficient expertise and experience to solve or prevent problems. The 8D Report consists of 8 disciplines that describe corrective measures based on the statistical analysis of the problem. This results in the following eight process steps:

Figure 1 – 8D report: the eight disciplines

D1 – Create a team

Mobilizing a good team is essential. The team must preferably be multidisciplinary. Due to a varied combination of knowledge, skills and experience, one can look at a problem from different perspectives.

Besides having an effective team leader, it is also advisable to record team structure, goals, different team roles, procedures and rules in advance so that the team can begin taking action quickly and effectively, and there is no room for misunderstandings.

D2 – Describe the problem

Define the problem as objectively as possible. The 5W2H analysis (who, what, when, where, why, how, how much) is a welcome addition to the problem analysis and can help to arrive at a clear description of the problem.

D3 – Interim containment action

It may be necessary to implement temporary fixes. For example, to help or meet a customer quickly or when a deadline has to be met. It is about preventing a problem from getting worse until a permanent solution is implemented.

D4 – Identify the root cause

Before a permanent solution is found, it is important to identify all possible root causes that could explain why the problem occurred. Various methods can be used for this purpose, such as the fishbone diagram (Ishikawa) which considers factors such as people, equipment, machines and methods or the 5 whys method.

All causes must be checked and/ or proven and it is good to check why the problem was not noticed at the time it occurred.

Take a look at our article on Root Cause Analysis , a method of problem solving that aims at identifying the root causes of problems or incidents.

D5 – Developing permanent corrective actions

As soon as the root cause of the problem has been identified, it is possible to search for the best possible solution. Again various problem solving methods can be used such as value analysis and creative problem solving.

From here, permanent corrective actions can be selected and it must be confirmed that the selected corrective actions will not cause undesirable side effects. It is therefore advisable to define contingency actions that will be useful in unforeseen circumstances.

D6 – Implementing permanent corrective actions

As soon as the permanent corrective actions are identified, they can be implemented. By planning ongoing controls, possible underlying root causes are detected far in advance.

The long term effects should be monitored and unforeseen circumstances should be taken into account.

D7 – Preventive measures

Prevention is the best cure. This is why additional measures need to be taken to prevent similar problems. Preventative measures ensure that the possibility of recurrence is minimised. It is advisable to review management systems, operating systems and procedures, so that they can be improved procedures if necessary.

D8 – Congratulate the team

By congratulating the team on the results realized, all member are rewarded for their joint efforts. This is the most important step within the 8D method; without the team the root cause of the problem would not have been found and fixed.

By putting the team on a pedestal and sharing the knowledge throughout the organization, team motivation will be high to solve a problem the next time it presents itself.

The 8D Report is also about teamwork

A strength of this method is its focus on teamwork. The team as a whole is believed to be better and smarter than the sum of the qualities of the individuals. Not every problem justifies or requires the 8D Report.

Furthermore, the 8D Report is a fact-based problem solving process, which requires a number of specialized skills, as well as a culture of continuous improvement. It could be that training of the team members is required before 8D can work effectively within an organization.

The team must recognize the importance of cooperation in order to arrive at the best possible solution for implementation.

What is the 8D Problem Solving? And How to use the 8D Report?

The 8D problem-solving process (also known as the 8 Disciplines) is very different from previous processes we explored previously, such as the Double Diamond process or the IBM Design Thinking. The 8D process works in a rigid standardised nature to address the crisis caused by problems. The 8D process aims to walk with the team to highlight the problem, its root causes and propose a long-term solution. The process is documented in an 8D report which includes details of each of the eight stages. At the end of this article, we will explore an example report, and you can find a free 8D report template to download.

In times of crisis, companies face the challenge of analysing and solving problems efficiently in a short time to save developed projects. Problem-solving techniques such as the  TRIZ method  and  Hurson’s Production Thinking Model  allow companies to overcome crises and solve problems using less effort and time.

Brief History of the 8D Problem Solving

The 8D method was first implemented by the US government during WW II as a military standard and was referred to as the Army Directive 1520, “Remedies and disposal of nonconforming materials.” In 1987, the demand for a team-oriented problem-solving method increased among the management organisation in the automotive industry to find a way to eliminate recurring issues.

Ford Motor Company published their manual,  Team Oriented Problem Solving (TOPS),  which includes their 8 Disciplines of the problem-solving process. The process was initially used to deal with quality control and safety issues inside the company but later expanded its role to a team approach problem-solving method. The 8D process is employed by engineers and designers to identify, analyse, and correct problems by eliminating the primary source that caused the problem.

So, what are the eight steps in the 8D methodology? The 8D problem solving process includes 8 Disciplines. In the mid-90s, a D0 step for planning was added to the process. The 8D steps include the following:

• D1: Team formation
• D2: Describe the problem
• D3: Develop a temporary containment plan
• D4: Determine and verify root causes
• D5: Verify the permanent solution
• D6: Implement the permanent solution
• D7: Prevent recurrence
• D8: Congratulate your team

The 8 Disciplines aim to achieve the following targets while solving the specified problem:

• Think as a team while solving the problem
• Isolate the situation and understand its causes
• Identify the factors that contribute to the problem
• Provide a temporary solution to halt the impact of the problem
• Eliminate the causes of the problem and the factors contributing to it
• Prevent the problem from recurring

When Should the 8D Problem Solving be Used?

Based on the above targets, the 8D problem solving process is designed for complex problems whose solution exceeds the ability of one expert. Also, it aims to establish communication for problem resolution through different levels inside the company. In some situations, the consumer or the management team requests the application of the 8D process through several forms or documentation.

While 8D problem solving is suitable for recurring problems that may repeatedly occur within a project or company, it is not ideal for simple issues that can be solved quickly by individual efforts. The process is unsuitable for a problem that can be solved with a straightforward solution. The 8D process is designed for complex issues, which require several weeks to solve and the involvement of at least four people.

8D problem solving provides a systematic process to find and solve problems. Therefore, if the situation requires choosing between alternative solutions, 8D acknowledges that other tools may help solve the problem better than the 8D process.

How to Apply the 8D Problem Solving Process?

The steps below form the 8 Discipline process to achieve targeted problem solving through the eight steps.

This discipline is also known as the Pre 8D because it aims to understand the problem and determine if the 8D process is the correct method to use. At this stage, the team aims to answer general questions such as:

• Is this a new problem, or has it happened before?
• Is this a recurring problem?
• What is the history of this issue?
• What was the method used to solve the problem before?

At this stage, the target is to learn about the problem’s history and decide if the 8D process is the best tool to solve the problem.

D1: Team Formation

Thinking as a team can produce more efficient solutions than trying to solve a problem alone. The team includes all the stakeholders involved in the situation. The team communicates with each other and performs brainstorming to solve the problem (check  Design Thinking Tools: Reverse Brainstorming ). If the team does not know each other, the brainstorming time can be used to learn how to teach members to explore ideas together. Methods can be used in brainstorming sessions such as mind mapping , Six Thinking Hats , and  Lego Serious Play.

D2: Describe the Problem

After team formation, the second step is to understand the problem and its risks. This stage starts with a risk analysis to identify the situation and how it can affect the project flow. Several methods can be used to analyse the problem from different perspectives, including  SWOT analysis ,  SCAMPER technique , and similar tools. This stage is essential to building a clear vision of the problem and ensuring all stakeholders have the same understanding of the situation.

D3: Develop a Temporary Containment Plan

While solving the problem, there should be a temporary containment plan to prevent the problem from affecting the rest of the project or the final product. This temporary containment solution is a short-term operation such as adding more labour, increasing the quality measurements, applying a risk plan, etc.

It is essential to understand that the containment action is not the real solution and can only be used for the short term. Therefore, this action can be applied internally and not affect the process of reaching a permanent solution.

D4: Determine and Verify Root Causes

This stage aims to investigate the root causes of the problem; it can be considered the core of the 8D problem solving process. In many problems, what we see as causes are symptoms of other root causes. This misunderstanding can lead to inaccurate attempts at solutions that can have negative consequences in the future and leave the underlying problem unsolved.

An intensive investigation should be implemented because, in many cases, the root cause is hidden inside the process and covered by many symptoms, which is confusing. Some tools can be used to define the root causes of the problem, such as  brainstorming , statistical analysis, flow charts, audits, etc.

D5: Verify the Permanent Solution

Once the root cause is defined, the solution becomes apparent, and the team better understands how to solve the problem. However, the symptoms and other related factors may create difficulties deciding how best to apply the solution. So, these other factors should be considered when determining the permanent solution to the dilemma.

When choosing the permanent solution to the problem, it should meet the following criteria to ensure it is the ideal solution for the problem:

• The solution should be practical
• The solution should be feasible
• The solution should be cost-effective
• The solution should not fail during production
• The solution should be implemented in all affected facilities in the company

D6: Implement the Permanent Solution

Once the solution is approved, this step tends to work as an action plan. This plan aims to outline the steps to implement the solution. It is common to ask questions in this stage: What should be done? Who should be involved in the correction plan?

More documentation and detailed plans should be created if the solution is complex and needs further procedures. The method may include training the team and checking the plan’s progress for further development and improvement.

D7: Prevent Recurrence

Once the action plan is set and ready to be implemented, the team should establish a plan to prevent the problem from occurring in the future. The action plan should be tested and documented as part of the process to avoid the recurrence of the problem. Some of the tools that can achieve this goal are Control Charts, Capabilities Analysis, and Control Plans.

D8: Congratulate the Team

After completing the task and implementing the solution, the team deserves an acknowledgement of their work and a celebration. This event will positively impact the stakeholders and reflect recognition of employees’ efforts from the management inside the company.

How do you Write an 8D Report?

The primary documentation used in the problem solving process is the 8D report. Korenko et al. (2013) presented an example of the 8D problem-solving application, Application 8D Method For Problems Solving . After this example, you can find a free 8D Report template that you can download and use for both commercial and noncommercial applications. The first part of the report, D0, includes information about the problem and the project details related to the project. D1 section contains details of the team involved in the project, roles, titles and contact information. D2 part of the report includes a detailed description of the problem and possible visual images to show the problem clearly. The report can consist of the type of damage of the failure and the function where the problem occurs (Figure 2).  

D3 includes details of the temporary solution for the problem required to stop the damage rapidly. In this part, the temporary remedy is described, particularly the symptoms affect, the responsibility, and the validation of the action. In D4, the team uses a root-cause method such as the 5WHYs or the Cause-Effect analysis (Fish Bone method). These methods help the team to identify the root causes of the problem. In Figure 3, the 5WHYs method is used several times to identify the root cause of the problem. 

D5 of the report provides details about the permanent solution to fix the problem. Unlike the temporary solution, this aims to element the root causes of the problem. This section includes the procedure’s name, the reason to use it, the responsibility, the management approval to apply it and the expected date of completing the utilisation of the solution, as seen in Figure 4. In the following stage, D6, the team provides details on the implementation and validation of the permanent action.

D7 provides details about preventing the recurrent problem, such as the name of the action after the validation process in the previous stage. Also, this stage provides details of the cause behind this action and elements about its responsibility and implementing details. Finally, in D8, the report includes a summary of the procedure and the proper approvals related to the procedure implementation (Figure 5).

The 8D Problem Solving process provides a reliable and systematic method that ensures that the problems inside a company or project are solved by eliminating their root causes and preventing recurrence. However, it is most suitable for complex problems that can take weeks or even months to solve. Therefore, the first stage aims to determine if the 8D process is ideal for the problem or if more straightforward tools should be implemented. If the 8D problem solving method is appropriate for your business problem, you have a step-by-step template to guide you through your attempts to find a suitable solution to the obstacle you need to overcome.

Introduction to Eight Disciplines of Problem Solving (8D)

The Eight Disciplines of Problem Solving (8D) is a problem solving methodology designed to find the root cause of a problem, devise a short-term fix and implement a long-term solution to prevent recurring problems. When it’s clear that your product is defective or isn’t satisfying your customers, an 8D is an excellent first step to improving Quality and Reliability.

Ford Motor Company developed this problem solving methodology, then known as Team Oriented Problem Solving (TOPS), in the 1980s. The early usage of 8D proved so effective that it was adopted by Ford as the primary method of documenting problem solving efforts, and the company continues to use 8D today.

8D has become very popular among manufacturers because it is effective and reasonably easy to teach. Below you’ll find the benefits of an 8D, when it is appropriate to perform and how it is performed.

What is Eight Disciplines of Problem Solving (8D)

The 8D problem solving process is a detailed, team oriented approach to solving critical problems in the production process. The goals of this method are to find the root cause of a problem, develop containment actions to protect customers and take corrective action to prevent similar problems in the future.

The strength of the 8D process lies in its structure, discipline and methodology. 8D uses a composite methodology, utilizing best practices from various existing approaches. It is a problem solving method that drives systemic change, improving an entire process in order to avoid not only the problem at hand but also other issues that may stem from a systemic failure.

8D has grown to be one of the most popular problem solving methodologies used for Manufacturing, Assembly and Services around the globe. Read on to learn about the reasons why the Eight Disciplines of Problem Solving may be a good fit for your company.

Why Apply Eight Disciplines of Problem Solving (8D)

The 8D methodology is so popular in part because it offers your engineering team a consistent, easy-to-learn and thorough approach to solving whatever problems might arise at various stages in your production process. When properly applied, you can expect the following benefits:

• Improved team oriented problem solving skills rather than reliance on the individual
• Increased familiarity with a structure for problem solving
• Creation and expansion of a database of past failures and lessons learned to prevent problems in the future
• Better understanding of how to use basic statistical tools required for problem solving
• Improved effectiveness and efficiency at problem solving
• A practical understanding of Root Cause Analysis (RCA)
• Problem solving effort may be adopted into the processes and methods of the organization
• Improved skills for implementing corrective action
• Better ability to identify necessary systemic changes and subsequent inputs for change
• More candid and open communication in problem solving discussion, increasing effectiveness
• An improvement in management’s understanding of problems and problem resolution

8D was created to represent the best practices in problem solving. When performed correctly, this methodology not only improves the Quality and Reliability of your products but also prepares your engineering team for future problems.

When to Apply Eight Disciplines of Problem Solving (8D)

The 8D problem solving process is typically required when:

• Safety or Regulatory issues has been discovered
• Customer complaints are received
• Warranty Concerns have indicated greater-than-expected failure rates
• Internal rejects, waste, scrap, poor performance or test failures are present at unacceptable levels

How to Apply Eight Disciplines of Problem Solving (8D)

The 8D process alternates inductive and deductive problem solving tools to relentlessly move forward toward a solution. The Quality-One approach uses a core team of three individuals for inductive activities with data driven tools and then a larger Subject Matter Expert (SME) group for the deductive activities through brainstorming, data-gathering and experimentation.

D0: Prepare and Plan for the 8D

Proper planning will always translate to a better start. Thus, before 8D analysis begins, it is always a good idea to ask an expert first for their impressions. After receiving feedback, the following criterion should be applied prior to forming a team:

Collect information on the symptoms

Use a Symptoms Checklist to ask the correct questions

Identify the need for an Emergency Response Action (ERA), which protects the customer from further exposure to the undesired symptoms

D1: Form a Team

A Cross Functional Team (CFT) is made up of members from many disciplines. Quality-One takes this principle one step further by having two levels of CFT:

• The Core Team Structure should involve three people on the respective subjects: product, process and data
• Additional Subject Matter Experts are brought in at various times to assist with brainstorming, data collection and analysis

Teams require proper preparation. Setting the ground rules is paramount. Implementation of disciplines like checklists, forms and techniques will ensure steady progress.  8D must always have two key members: a Leader and a Champion / Sponsor:

• The Leader is the person who knows the 8D process and can lead the team through it (although not always the most knowledgeable about the problem being studied)
• The Champion or Sponsor is the one person who can affect change by agreeing with the findings and can provide final approval on such changes

D2: Describe the Problem

The 8D method’s initial focus is to properly describe the problem utilizing the known data and placing it into specific categories for future comparisons. The “Is” data supports the facts whereas the “Is Not” data does not. As the “Is Not” data is collected, many possible reasons for failure are able to be eliminated. This approach utilizes the following tools:

• Problem Statement
• Affinity Diagram (Deductive tool)
• Fishbone/Ishikawa Diagram (Deductive tool)
• Problem Description

D3: Interim Containment Action

In the interim, before the permanent corrective action has been determined, an action to protect the customer can be taken. The Interim Containment Action (ICA) is temporary and is typically removed after the Permanent Correct Action (PCA) is taken.

• Verification of effectiveness of the ICA is always recommended to prevent any additional customer dissatisfaction calls

D4: Root Cause Analysis (RCA) and Escape Point

The root cause must be identified to take permanent action to eliminate it. The root cause definition requires that it can be turned on or off, at will. Activities in D4 include:

• Comparative Analysis listing differences and changes between “Is” and “Is Not”
• Development of Root Cause Theories based on remaining items
• Verification of the Root Cause through data collection
• Review Process Flow Diagram for location of the root cause
• Determine Escape Point, which is the closest point in the process where the root cause could have been found but was not

D5: Permanent Corrective Action (PCA)

The PCA is directed toward the root cause and removes / changes the conditions of the product or process that was responsible for the problem. Activities in D5 include:

• Establish the Acceptance Criteria which include Mandatory Requirements and Wants
• Perform a Risk Assessment /  Failure Mode and Effects Analysis (FMEA) on the PCA choices
• Based on risk assessment, make a balanced choice for PCA
• Select control-point improvement for the Escape Point
• Verification of Effectiveness for both the PCA and the Escape Point are required

D6: Implement and Validate the Permanent Corrective Action

To successfully implement a permanent change, proper planning is essential. A project plan should encompass: communication, steps to complete, measurement of success and lessons learned. Activities in D6 include:

• Develop Project Plan for Implementation
• Communicate the plan to all stakeholders
• Validation of improvements using measurement

D7: Prevent Recurrence

D7 affords the opportunity to preserve and share the knowledge, preventing problems on similar products, processes, locations or families. Updating documents and procedures / work instructions are expected at this step to improve future use. Activities in D7 include:

• Review Similar Products and Processes for problem prevention
• Develop / Update Procedures and Work Instructions for Systems Prevention
• Capture Standard Work / Practice and reuse
• Assure FMEA updates have been completed
• Assure Control Plans have been updated

D8: Closure and Team Celebration

Teams require feedback to allow for satisfactory closure. Recognizing both team and individual efforts and allowing the team to see the previous and new state solidifies the value of the 8D process. Activities in D8 include:

• Archive the 8D Documents for future reference
• Document Lessons Learned on how to make problem solving better
• Before and After Comparison of issue
• Celebrate Successful Completion

8D and Root Cause Analysis (RCA)

The 8D process has Root Cause Analysis (RCA) imbedded within it. All problem solving techniques include RCA within their structure. The steps and techniques within 8D which correspond to Root Cause Analysis are as follows:

• Problem Symptom is quantified and converted to “Object and Defect”
• Problem Symptom is converted to Problem Statement using Repeated Whys
• Possible and Potential Causes are collected using deductive tools (i.e. Fishbone or Affinity Diagram)
• Problem Statement is converted into Problem Description using Is / Is Not
• Problem Description reduces the number of items on the deductive tool (from step 3)
• Comparative Analysis between the Is and Is Not items (note changes and time)
• Root Cause theories are developed from remaining possible causes on deductive tool and coupled with changes from Is / Is Not
• Compare theories with current data and develop experiments for Root Cause Verification
• Test and confirm the Root Causes

Example: Multiple Why Technique

The Multiple / Repeated Why (Similar to 5 Why) is an inductive tool, which means facts are required to proceed to a more detailed level. The steps required to determine problem statement are:

• Problem Symptom is defined as an Object and Defect i.e. “Passenger Injury”
• Why? In every case “SUV’s Roll Over”
• Why? In every case, it was preceded by a “Blown Tire”
• Why? Many explanations may be applied, therefore the team cannot continue with another repeated why past “Blown Tire”
• Therefore, the Problem Statement is “Blown Tire”
• Why? Low (Air) Pressure, Tire Defect (Degradation of an Interface) and High (Ambient) Temperature
• Counter measures assigned to low pressure and tire defect

This example uses only 4 of the 5 Whys to determine the root causes without going further into the systemic reasons that supported the failure. The Repeated Why is one way to depict this failure chain. Fault Tree Analysis (FTA) could also be used.

8D Problem Solving Process

Solving major problems in a disciplined way.

By the Mind Tools Content Team

(Also known as Global 8D Problem Solving)

When your company runs into a major problem, you need to address it quickly. However, you also need to deal with it thoroughly and ensure that it doesn't recur – and this can take a lot of effort and elapsed time.

The 8D Problem Solving Process helps you do both of these seemingly-contradictory things, in a professional and controlled way. In this article, we'll look at the 8D Problem Solving Process, and we'll discuss how you can use it to help your team solve major problems.

Origins of the Tool

The Ford Motor Company® developed the 8D (8 Disciplines) Problem Solving Process, and published it in their 1987 manual, "Team Oriented Problem Solving (TOPS)." In the mid-90s, Ford added an additional discipline, D0: Plan. The process is now Ford's global standard, and is called Global 8D.

Ford created the 8D Process to help teams deal with quality control and safety issues; develop customized, permanent solutions to problems; and prevent problems from recurring. Although the 8D Process was initially applied in the manufacturing, engineering, and aerospace industries, it's useful and relevant in any industry.

The eight disciplines are shown in figure 1, below:

Figure 1: The 8D Problem Solving Process

The 8D Process works best in teams tasked with solving a complex problem with identifiable symptoms. However, you can also use this process on an individual level, as well.

Applying the Tool

To use the 8D Process, address each of the disciplines listed below, in order. Take care not to skip steps, even when time is limited; the process is only effective when you follow every step.

Discipline 0: Plan

Before you begin to assemble a team to address the problem, you need to plan your approach. This means thinking about who will be on the team, what your time frame is, and what resources you'll need to address the problem at hand.

Discipline 1: Build the Team

You should aim to put together a team that has the skills needed to solve the problem, and that has the time and energy to commit to the problem solving process.

Keep in mind that a diverse team is more likely to find a creative solution than a team of people with the same outlook (although if outlooks are too diverse, people can spend so much time disagreeing that nothing gets done).

Create a team charter that outlines the team's goal and identifies each person's role. Then, do what you can to build trust and get everyone involved in the process that's about to happen.

If your team is made up of professionals who haven't worked together before, consider beginning with team-building activities to ensure that everyone is comfortable working with one another.

Discipline 2: Describe the Problem

Once your team has settled in, describe the problem in detail. Specify the who, what, when, where, why, how, and how many; and use techniques like CATWOE and the Problem-Definition Process to ensure that you're focusing on the right problem.

Start by doing a Risk Analysis – if the problem is causing serious risks, for example, to people's health or life, then you need to take appropriate action. (This may include stopping people using a product or process until the problem is resolved.)

If the problem is with a process, use a Flow Chart , Swim Lane Diagram , or Storyboard to map each step out; these tools will help your team members understand how the process works, and, later on, think about how they can best fix it.

Discovering the root cause of the problem comes later in the process, so don't spend time on this here. Right now, your goal is to look at what's going wrong and to make sure that your team understands the full extent of the problem.

Discipline 3: Implement a Temporary Fix

Once your team understands the problem, come up with a temporary fix. This is particularly important if the problem is affecting customers, reducing product quality, or slowing down work processes.

Harness the knowledge of everyone on the team. To ensure that each person's ideas are heard, consider using brainstorming techniques such as Round Robin Brainstorming or Crawford's Slip Writing Method , alongside more traditional team problem solving discussions.

Once the group has identified possible temporary fixes, address issues such as cost, implementation time, and relevancy. The short-term solution should be quick, easy to implement, and worth the effort.

Discipline 4: Identify and Eliminate the Root Cause

Once your temporary fix is in place, it's time to discover the root cause of the problem.

Conduct a Cause and Effect Analysis to identify the likely causes of the problem. This tool is useful because it helps you uncover many possible causes, and it can highlight other problems that you might not have been aware of. Next, apply Root Cause Analysis to find the root causes of the problems you've identified.

Once you identify the source of the problem, develop several permanent solutions to it.

If your team members are having trouble coming up with viable permanent solutions, use the Straw Man Concept to generate prototype solutions that you can then discuss, tear apart, and rebuild into stronger solutions.

Discipline 5: Verify the Solution

Once your team agrees on a permanent solution, make sure that you test it thoroughly before you fully implement it, in the next step.

• Conducting a Failure Mode and Effects Analysis (FMEA) to spot any potential problems.
• Using Impact Analysis to make sure that there will be no unexpected future consequences.
• Using Six Thinking Hats to examine the fix from several different emotional perspectives.

Last, conduct a Blind Spot Analysis to confirm that you and your team haven't overlooked a key factor, or made an incorrect assumption about this solution.

Discipline 6: Implement a Permanent Solution

Once your team reaches a consensus on the solution, roll your fix out. Monitor this new solution closely for an appropriate period of time to make sure that it's working correctly, and ensure that there are no unexpected side effects.

Discipline 7: Prevent the Problem From Recurring

When you're sure that the permanent solution has solved the problem, gather your team together again to identify how you'll prevent the problem from recurring in the future.

You might need to update your organization's standards, policies, procedures, or training manual to reflect the new fix. You'll likely also need to train others on the new process or standard. Finally, you'll need to consider whether to change your management practices or procedures to prevent a recurrence.

Discipline 8: Celebrate Team Success

The last step in the process is to celebrate and reward your team's success . Say "thank you" to everyone involved, and be specific about how each person's hard work has made a difference. If appropriate, plan a party or celebration to communicate your appreciation.

Before the team disbands, conduct a Post-Implementation Review to analyze whether your solution is working as you thought, and to improve the way that you solve problems in the future.

In the late 1980s, Ford Motor Company developed the 8D (8 Disciplines) Problem Solving Process to help manufacturing and engineering teams diagnose, treat, and eliminate quality problems. However, teams in any industry can use this problem solving process.

The eight disciplines are:

• Build the Team.
• Describe the Problem.
• Implement a Temporary Fix.
• Identify and Eliminate the Root Cause.
• Verify the Solution.
• Implement a Permanent Solution.
• Prevent the Problem From Recurring.
• Celebrate Team Success.

The 8D Problem Solving Process is best used with a team solving complex problems; however, individuals can also use it to solve problems on their own.

8D Manufacturing Report: Your Guide to Effective Problem Solving

• Written by Brecht Plasschaert
• Compliance , Lean Manufacturing
• Updated on January 10, 2024
• Published on August 16, 2022

Manufacturing companies are the backbone of any economy. They produce goods for local or international markets, employ people, and keep their customers happy. 

That’s why manufacturers often use 8D reports to identify and solve problems before they impact their production and business to ensure the quality of produced goods. The methodology was developed by Toyota Motors Manufacturing (TMM) in Japan in the 1960s to help the company achieve better performance. 

For companies who want to compete with other manufacturers around the world, it’s essential to identify and track root causes of non-conformities or problems in a production environment. This helps them achieve a high level of product efficiency and quality, which translates into lower costs and higher profits. 

In this article we cover the ins and outs of 8D reporting, how to use it, and the advantages it may offer to your workforce.

Download our 8D template as well to make your problem-solving process simpler.

The 8D method structure

The 8D problem-solving method is a systematic approach to problem solving that emphasizes team participation. This method generally covers:

• Identifying the Problem — You must first identify what is wrong with the process or operation.
• Determining Causes — After identifying a problem, you will have to determine its root cause(s). This may not be easy, but it’s imperative if you want to fix your processes and prevent future problems from arising again.
• Developing Corrective Action — Once you’ve identified the causes of your problems and analyzed all possible solutions, it’s time to develop corrective actions. Create a plan for how each possible solution would work (i.e., “if we use this part instead,” or “if we add these people,” etc.). You’ll also need metrics and checkpoints throughout this process to ensure that everything is working as intended.

The 8 disciplines

The eight disciplines (8D) follow a logical sequence of eight steps. It’s one of the most common methods used in manufacturing because it’s a structured approach, but it can also be applied to other industries.

D1: Create a team When using 8D, it is important to have a cross-functional team with individuals from different disciplines to assist you cover more territory. There should be two subgroups for the team members:

• Core members: people who are more data-driven and typical product, process, and data experts.
• Subject Matter Experts (SME): members who may contribute to brainstorming, research, and process observation. Bring in fresh SMEs without hesitation to assist with any step of the process.

These team members have to be equipped with the knowledge necessary to identify the issue and implement solutions.

D2: Describe the problem

The problem description is a narrative that describes the issue in detail and should be understood across the team members. It explains how the issue happened, what impact it had on your business, and why you need to fix it. The problem description should include:

• The underlying causes of your problem (the root cause). Why did this happen?
• What’s the impact of this issue? How much money are you losing because of this? What other problems does it cause within your company?
• How will fixing these underlying causes help solve or prevent future issues related to this one?

Here are some techniques and tools to identify and formulate the problems:

• 5 Why’s formulation
• Affinity Diagram
• Fishbone Diagram
• Is / Is Not method

D3: Develop a containment plan

Once you have identified, isolated, and controlled your manufacturing process problems, it’s time to create a plan for containment. You need clear descriptions so that everyone understands what they’re supposed to do in order to solve this issue. Be aware, an Interim Containment Action (ICA) is a temporary plan and should only be replaced with the Permanent Corrective Action (PCA) after completing 8D.

D4: Root Cause Analysis (RCA) and Escape Point

You might find yourself wandering down several rabbit holes before reaching this point. Be patient and methodical as you work through each step in your investigation process. This process should always be guided by facts rather than assumptions or guesses about what could be going wrong behind closed doors at your company’s factories overseas!

Review your results, then talk with your team about potential causes of the issue. Each probable root cause is mapped to the issue statement and any associated test results as part of the root cause analysis. Be cautious to rule out all probable reasons; hazy brainstorming and careless analysis might lead you to miss important details.

Some methods during this step include:

• Comparative Analysis
• Development of Root Cause Theories
• Verification of Root Cause Theories
• Review Process Flow Diagrams
• Determine Escape Points, the closest point in the process where root cause could be found

In addition to determining the underlying causes, attempt to remember when and why you first discovered the issue in the process. This is called an escape point, and there can be more than one.

D5: Formulate Permanent Corrective Actions (PCA)

Corrective actions should be based on the root cause analysis. The first step in formulating corrective actions is to determine the root cause of the failure mode. To do this, you will need to analyze all of your data and identify which potential factors contributed to the problem. Once you have determined what caused the failure, you can then come up with ways of preventing similar failures from occurring in the future.

For example, if an assembly line stops due to an electrical issue with one machine, it would not make sense to fix just one machine; rather, you should look at all machines on that line and make sure they have proper electrical connections so that they are able to function properly.

So when something goes wrong, you will have a plan for fixing it before it causes even bigger problems down the road. There are several steps involved in creating an effective corrective action plan:

• Plan out how long it will take before implementing any changes that can help fix whatever issue has arisen;
• Create an actionable plan detailing exactly what needs changing;
• Check in at regular intervals on progress made toward completing this project so that no one gets forgotten along its path until completion (this includes monitoring by both parties involved)
• If necessary take appropriate steps like adding more resources or reallocating existing ones when delays  arise from unforeseen factors such as weather conditions etc .”

D6: Implement and Validate the Permanent Corrective Action

Interim measures are temporary solutions to a problem. They can be used to prevent further damage or to allow time for a permanent solution to be implemented. Interim measures can also be used to reduce the impact of the problem until it is solved.

When you have identified an issue in your business, create an action plan that includes interim measures as well as final goals and expectations. If there is some sort of delay in implementing these interim measures, report back on progress at least monthly so management stays up-to-date on what is happening within your department and company at large.

Some activities during the 6D step include:

• Creating a project plan
• Share the plan with relevant parties.
• Use metrics to verify progress

D7: Monitoring of corrective measures

Monitoring is a key part of the 8D method. Monitoring is a way to check if a corrective action is working, or if it needs to be changed or completed. It’s also a way to check if the root cause has been addressed, and if your company has learned anything new from the incident that could help prevent future errors.

Your team needs to retain and document the shared knowledge that was gained while identifying, resolving, and preventing this problem. It’s important to review existing documents or procedures and update them accordingly to improve future outcomes.

Activities you need to keep in mind during this step are:

• Reviewing comparable products and procedures to avoid other problems.
• Creating or updating work instructions and procedures.
• Capturing new industry standards and procedures.
• Confirming the most recent failure mode and effect analysis (FMEA).
• Confirming the revision of control plans.

D8: Recognize team and individual efforts

Giving feedback to ensure a good outcome is crucial for any team to flourish. Recognize the efforts and labor that each person has put into what they have brought to the process at this moment.

The tasks in this stage consist of:

• Archive 8D for later use.
• Keep track of your learnings to enhance your problem-solving techniques.
• Comparisons of the before and after
• Celebration and acknowledgement of the group

How to Write an 8D report for your company when you have a product defect or a problem to solve?

An 8D report is a tool for managing a problem. It consists of eight columns and four rows:

• The first row, called the title row, lists each column’s name.
• Define the Problem
• Determine Causes
• Develop Solutions
• Verify Solutions
• Control Risks
• Document Your Improvements and Lessons Learned (optional)
• Closeout (optional).
• 1a through 7a include action steps related to 1 through 7 above; 
• 6b includes an optional section that can be used if it becomes necessary to document lessons learned from this process at some later time (e.g., after you implement Solution 3b).

8D Report Pros and Cons for manufacturers

8d report advantages:.

More awareness of the root cause (s)

It improves your quality control processes by identifying the potential causes of nonconformance at each stage of production and prioritizes corrective action steps based on their risk level, priority, impact, probability, etc., thus ensuring that you address the system issues first before they result in incurring costs due to rework/scrap or adverse customer response or regulatory intervention.

Enhanced quality control strategies and plans.

8D enables you to reduce lead times by identifying where bottlenecks are occurring within a process so that resource allocation can be adjusted accordingly in order to improve throughput while maintaining quality standards (i.e., having sufficient workers available at all stages). This can also help with preventing employee burnout by covering more shifts so there is less overtime required from employees who might otherwise be tired from working too many hours without breaks when there is high demand for their services during peak times (like Christmas shopping season).

Avoid future problems

The 8D report can help your manufacturing company avoid costly mistakes, as you can see exactly where problems may occur and take action to prevent them. 

Team-based approach

An 8D report gives you an opportunity to check if everything is running smoothly and confirm that everyone understands their tasks and responsibilities. With this information at hand, it’s easier to make improvements based on what works best or needs improvement in different areas of your business. In addition, it’s easy to access historical data on procedures and products.

Better communication flows

Finally, It also allows for better communication flows between teams responsible for different processes in the manufacturing process and reduces the amount of time spent investigating issues that aren’t really problems.

8D report Cons: 

Extensive training

There aren’t many cons to applying 8D problem solving techniques. The most important one is that it will require that people who take part in problem-solving activities obtain the right training and instructions on how 8D operates.

They will also need to comprehend other closely linked concepts related to 8D issue solving methodologies. Examples of these may be pareto charts , process maps, fishbone diagrams, and more.

Lack in flexibility

In addition, an 8D report is not a good tool when there are several problems at once or when an issue in the manufacturing process needs immediate attention. 

Dedicated budget

An 8D report also has requirements that smaller enterprises with fewer resources can find complicated and costly. For example: you need to have a dedicated budget to provide extensive training so your team has the right knowledge to do the job right. 

Technology to Assist in 8D Reporting for manufacturers

There are a number of software solutions available to help companies implement 8D programs and manage their Supplier Quality Management (SQM) efforts. 

Why should you digitize your 8D processes?

Automating the 8D report process will ensure that all problems are captured and reported consistently, with no one falling through the cracks.

It facilitates collaboration across teams and departments. All stakeholders will have access to information on the status of every problem as it progresses through its lifecycle, so they can respond quickly if an issue arises or make suggestions for how best to resolve it. This saves time and allows everyone involved in a particular issue to feel more connected with one another than they otherwise would be able to do without this kind of technology at their disposal.

8D Solutions

8D reporting is a powerful tool for monitoring progress and identifying issues in manufacturing. This can help you improve your processes, reduce cost, and increase profits. With the help of technology, you can easily keep track of your 8D reports. Here are some solutions to assist manufacturers with this process:

A program like SAP or Oracle ERP allows you to integrate 8D reporting into your system. This way, all information is in one place and updated automatically.

A no-code software tool like Azumuta allows you to integrate 8D reporting into your system. This way, all information is in one place and updated automatically. Easily capture data with your phone or tablet , while offline from the field at any time! Create an 8D report right away and distribute it to your stakeholders and coworkers and track corrective actions to team members through a single app.

With real-time data, companies can improve communication among team members, improve problem solving skills for individuals on the team (including managers), and develop new solutions for existing issues based on past experience with similar problems at other locations or companies.

Microsoft Office

If you don’t want to invest in new software at this time but still want an easy way to manage your project issues and progress, consider using an online database like Excel for managing risks, defects, quality assurance methods, etc. This will allow you to access information from anywhere with a laptop or mobile device. This way is rather tedious though and important information can be lost.

Digitize your 8D Processes

As you can see, there are many benefits to using a software for 8D reporting. While it may seem like a lot of work initially, once you get the hang of it, it will be easy to maintain and manage your 8D records. The most important thing is to start now! Make sure that your company gets started on an 8D reporting software today so that your team can begin documenting problems as soon as possible!

8D Problem Solving is a systematic and structured approach used to solve business related problems. It names has been given by the fact there are 8 steps or 8 disciplines that are followed to identify, correct and eliminate recurring problems.

8D Problem Solving is regarded as robust methodology that has proven its worth across multiple industries and manufacturing in particular. The methodology was Initially developed within the automotive industry, it has since been widely adopted in manufacturing, logistics and health care to name a few. The 8D approach goes beyond helping team just identify the root cause of problem but also provides a structured approach for implementing and verifying corrective actions.

Table of Contents

What is 8d problem solving.

The 8D Problem-Solving methodology was developed in the late 1980s  by Ford Motor Company. The term “8D” stands for “Eight Disciplines,” which represent the eight critical steps in problem-solving.

Initially it was only intended to resolve issues within the automotive manufacturing process. However, over the year since then the methodology has gained universal acceptance and is now applied across various sectors. The 8D approach was heavily influenced by quality management systems like Total Quality Management (TQM) and methodologies like Six Sigma and forms a key part of quality roles and Six sigma qualifications.

8D is also encourages collaborative team based approach to addressing issues in the workplace This methodology was purposefully designed to be a cross-functional effort, ensuring to bring together expertise from different departments or disciplines to comprehensively address an issue by looking at it from all point of view. Here are the key components:

Preparation : Before diving into problem-solving, the team gathers all necessary resources and tools.

Team Establishment : A cross-functional team is assembled, each member having a specific role and responsibility.

Problem Description : The issue at hand is clearly defined to ensure everyone has a shared understanding.

Interim Actions : Short-term solutions are implemented to contain the problem and prevent further damage.

Root Cause Analysis : Various tools and methods are used to identify the real cause of the problem.

Permanent Corrective Actions : Long-term solutions are selected and verified to eliminate the root cause.

Implementation : The long-term solutions are implemented across the board, including necessary changes to policies and procedures.

Prevent Recurrence : Measures are taken to ensure that the problem does not occur again.

Team Recognition : The team is congratulated and acknowledged for their efforts.

How does 8D Compare to over Problem-Solving Methods?

Between quality management systems and lean six sigma there are several problem-solving methodologies such as PDCA (Plan-Do-Check-Act), DMAIC (Define-Measure-Analyze-Improve-Control), and A3 . However the combination of the 8D steps results in a comprehensive frame work that is:

Team-Oriented : Unlike some methodologies that can be carried out by individuals, 8D strongly emphasizes team collaboration as a core principle as seen in steps D1 and D8.

Structured Framework : 8D provides a very detailed, step-by-step guide for solving complex problems, by breaking it down in to logical steps making it easier to manage and track progress.

Broad Applicability : While some methodologies like DMAIC are closely tied to Six Sigma, 8D can be applied in various contexts without being tied to a particular quality management system.

Focus on Prevention : 8D not only aims to solve the problem but also focuses on implementing changes to prevent its recurrence, making it a complete approach to problem solving.

The 8 Disciplines Explained

D0: prepare for the process.

Before you start 8D you should prepare for the 8D process. This phase sets the foundation for the entire methodology, ensuring that the team is able to tackle the problem effectively. Therefore, effective preparation helps in avoiding unnecessary delays and ensures that you’re not solving the wrong problem.

Within the initial preparation step you should also the time to think about what knowledge, expertise and experience you need within the team. Cross-functional teams are important, as they bring alternative perspectives and skills to the table rather than everyone looking at the problem from one point of view. Make sure you consider expertise, availability, and interest when selecting team members.

D1: Establish the Team

In D1 you should establish the team by clearly defining the roles and responsibilities for each team member. This includes assigning a team leader, subject matter experts, and roles for data collection , analysis, and communication this helps to provide the team members clarity on how they will be involved and contribute to the success of the problems solving activity.

Team Composition

Once roles are defined, where possible ensure that the team is balanced in terms of skills and expertise. A well-rounded team will be more effective in tackling various aspects of the problem.

Communication

Establish clear methods communication, both within the team and with external stakeholders. Such as deciding on regular meeting schedules that everyone can attend, reporting formats, and tools for collaboration.

D2: Describe the Problem

In D2 it is time to create a well formed problem statement. This step is key as it provides a foundation for understanding the problem which will lead to generally more successful problem-solving. It ensures that everyone clearly understands what needs to be addressed, setting the scope for the entire process. Ensure that the problem is clearly understood by everyone in the team at this stage to prevent confusion later on in the process.

5W1H Method of creating a Problem Definition

Use data gathering techniques such as observations, interviews, and document reviews can help to precisely identify the problem. A useful tool to use at this stage could be the 5W1H Problem definition method.

You can find out more about this method with our 5W1H guide .

Problem Definition – is / is not template

When creating your problem definition ensure to be specific, measurable, and unambiguous when stating the problem. You should avoid generalities and ensure that the problem statement is understandable to someone unfamiliar with the issue. If you are new to this process it may be helpful to give the statement to someone unfamiliar to the process and see if they understand it or if they have questions. You can then clarify any questions by adjusting the problem description to improve the claity.

D3: Implement and Verify Interim Actions

In D3 while the team is investigating the root cause, interim actions are must be implement to contain the problem and minimize its impact. This is particularly important in critical situations affecting safety, compliance, or customer satisfaction. 

In this step you should identify, plan, and execute short-term fixes that can quickly contain the problem. This could include quarantining the product to ensure it is not sent out to the customer or even pausing production lines that continue to product defects. Ensure these actions are documented for future reference.

Use metrics and KPIs to gauge the effectiveness of the interim actions. Make adjustments as necessary.

D4: Root Cause Analysis

D4 is where you start to understand what is causing the issue by identifying the underlying reason for the problem. The objective is to find the root cause, not just the symptoms.

At this stage there are a range of quality and lean six sigma tools that can be used to conduct root cause analysis , which can include the Fishbone Diagram for structured brainstorming and the 5 Whys technique for causal chain analysis.

We have a range of guides on all of these techniques for you to use.

Once identified, it is important validate the root cause through experimentation or additional data analysis to ensure it’s the actual cause and not a symptom, this can often be an overlook critical step in the root cause process.

D5: Choose and Verify Permanent Corrective Actions

In D5 you need to choose what actions to be taken to prevent the problem reoccurring and any solutions implemented should be verified that the actions correct the problem this can involve trial runs, further data collection and inspections of product or services being produced.

You should also consider factors like cost, impact, and feasibility when choosing a permanent corrective action and should also conduct a risk assessment to evaluate potential negative outcomes of the actions taken

An implementation or action plan is often useful to document at this stage to detail the steps for implementation, assign responsibilities, and set timelines.

D6: Implement Permanent Corrective Actions

Once verified, implement the corrective actions across all relevant departments or processes. This can involved documenting the new process and training out to all stakeholders involved to ensure the new process is followed and that the stakeholders understand the reason for the change.

At this point you should continue to regularly monitor the situation to ensure the corrective actions are sustained and effective, this could be for a period of 30, 60 or 90 days after the problem was resolved to ensure the new process has become a sustained and issues do not reoccur. 

D7: Prevent Recurrence

In D7 to prevent recurrent you should review and update organizational policies or standard operating procedures (SOPs) to prevent a recurrence of the problem and document the new standard process

It is important to conduct regular reviews to continuously monitor the process and ensure procedures are being followed but also to identify further opportunities for process improvement.

D8: Congratulate the Team

The final step D8, after the hard work and successful problem resolution, it is important to acknowledging and congratulating the team is vital for morale and future engagement. With the recognition of a successful 8D Problem-solving activity complete you are more likely to encourage future participation as the method gets a reputation as being useful and successful at solving problems. 

Whether it’s a team lunch, certificates of achievement, or simply a public acknowledgment, celebrate the success in a way that resonates with your team.

Finally it is always important to conduct a lessons-learned session and document the insights gained during the process for future reference. This can be used as a future point of reference for problem solving activities.

Mastering the art of problem-solving is crucial in today’s complex and fast-paced environment. The 8D Problem-Solving methodology offers a structured, team-based approach to tackling challenges that can arise in any sector, be it manufacturing, public services, or logistics.

Measuring the Effectiveness of 8D Problem-Solving Efforts

Problem solving is a vital skill for any business that wants to survive and thrive in today’s competitive and dynamic environment. However, not all problems are created equal. Some are simple and straightforward, while others are complex and multifaceted. How can businesses effectively tackle these challenging problems and prevent them from recurring?

One of the most powerful and proven problem-solving methodologies is 8D problem solving. 8D stands for eight disciplines, which are a series of steps that guide teams through the process of identifying, analyzing, resolving, and preventing problems. 8D problem solving can help businesses improve their quality, reduce their costs, and enhance their customer satisfaction.

What is 8D Problem Solving

8D problem solving is a structured and systematic approach to solving complex problems that require cross-functional collaboration and root cause analysis. It was developed by Ford Motor Company in the late 1980s as a way to address customer complaints and improve product quality. Since then, it has been widely adopted by many organizations across various sectors.

The core principles and objectives of 8D problem solving are:

• Focus on the customer’s needs and expectations
• Involve a multidisciplinary team with relevant expertise and authority
• Use data and facts to support decision making
• Identify and eliminate the root causes of the problem
• Implement corrective actions that prevent reoccurrence
• Document and communicate the problem-solving process and results

The 8D methodology differs from other problem-solving approaches in several ways. First, it emphasizes team-oriented problem-solving. Second, it follows a sequential and logical order of steps that ensures thoroughness and consistency. Third, it uses various tools and techniques to facilitate analysis and action. Fourth, it incorporates feedback loops and verification methods to ensure effectiveness and sustainability.

The Eight Disciples of Problem Solving

D1: establish the team.

The first step in the 8D approach is to form a team that will work on the problem. The team should consist of members who have knowledge, experience, or involvement in the problem area. The team should also have a leader who will coordinate the activities and communicate with stakeholders.

The purpose of establishing the team is to:

• Define the roles and responsibilities of each team member
• Establish the scope and boundaries of the problem
• Set the goals and expectations for the problem-solving process
• Allocate the resources and time required for the process

D2: Describe the Problem

The second step in this problem-solving method is to define and describe the problem in detail. The team should use data and facts to describe the problem as accurately as possible. The team should also use tools such as the 5W2H method (who, what, where, when, why, how, how much), Six Sigma, or an IS/IS NOT matrix to clarify the aspects of the problem.

Defining and describing the problem allows businesses to:

• Establish a common understanding of the problem among the team members
• Identify the symptoms, effects, and impacts of the problem
• Quantify the magnitude and frequency of the problem
• Specify the criteria for evaluating potential solutions

D3: Develop Interim Containment Actions

The third step in 8D problem solving is to develop interim containment actions that will prevent or minimize the negative consequences of the problem until a permanent solution is found. The team should identify and implement actions that will isolate, control, or eliminate the causes or sources of variation that contribute to the problem.

When you develop interim containment actions, you:

• Protect the customer from defective products or services
• Reduce the risk of further damage or harm
• Maintain operational continuity and stability
• Buy time for root cause analysis and corrective actions

D4: Determine Root Causes

The fourth step in the 8D method is to determine the root causes responsible for creating or allowing the problem to occur. The team should use data analysis tools such as Pareto charts, histograms, scatter plots, or fishbone diagrams to identify possible causes. The team should also use root cause analysis techniques such as 5 Whys, fault tree analysis, or Failure Modes and Effect Analysis (FMEA) to verify or validate the causes.

The purpose of determining root causes is to:

• Understand why the problem happened
• Identify all possible factors that influence or contribute to the problem
• Eliminate superficial or symptomatic causes
• Prevent jumping to conclusions or making assumptions

D5: Choose Permanent Corrective Actions

The fifth step in 8D problem solving is to choose permanent corrective actions that will address or remove root causes permanently. The team should generate multiple possible solutions using brainstorming techniques such as SCAMPER (substitute, combine, adapt, modify, put to another use, eliminate, reverse) or TRIZ (theory of inventive problem solving). The team should also evaluate each solution using criteria such as feasibility, effectiveness, cost, risk, or impact.

Choosing permanent corrective actions helps to:

• Select the best solution that meets customer needs and expectations
• Ensure that root causes are eliminated or prevented from recurring
• Consider trade-offs between different solutions
• Plan for implementation challenges or barriers

D6: implement permanent corrective actions.

The sixth step in 8D problem solving is to implement permanent corrective actions that were chosen in D5. The team should develop an action plan that specifies who will do what by when using tools such as Gantt charts or PDCA cycles (plan-do-check-act). The team should also execute the action plan according to schedule using tools such as checklists or standard operating procedures.

The purpose of implementing permanent corrective actions is to:

• Put the chosen solution into practice
• Monitor progress and performance during implementation
• Resolve any issues or problems that arise during the implementation
• Document changes or modifications made during implementation

D7: Prevent Recurrence

The seventh step in 8D problem solving is to prevent recurrence by ensuring that permanent corrective actions are effective and sustainable. The team should verify that root causes have been eliminated using tools such as control charts or statistical process control (SPC). The team should also validate that customer requirements have been met using tools such as surveys or audits.

Preventing reoccurrence helps to:

• Confirm that permanent corrective actions have solved the problem
• Evaluate customer satisfaction with products or services after implementation
• Identify opportunities for further improvement or optimization
• Standardize best practices or lessons learned from implementation

D8: Recognize Team Efforts

The eighth step in 8D problem solving is recognizing team efforts by acknowledging their contributions and achievements throughout the process. The team should celebrate their success by sharing their results with stakeholders using tools such as reports or presentations. The team should also appreciate their efforts by rewarding them with recognition or incentives.

The purpose of recognizing team efforts is to:

• Motivate team members for future challenges
• Build trust and rapport among team members
• Enhance team morale and cohesion
• Promote a culture of continuous improvement

Implementing 8D Problem-Solving Methodology

Implementing an 8D problem-solving methodology can be challenging for many businesses due to various factors such as organizational culture, resources, or complexity. However, with proper planning, preparation, and execution, it can be done successfully.

Here is some practical guidance on how businesses can effectively implement the 8D process:

Define clear roles & responsibilities for each discipline

One of the key factors for successful implementation is having clear roles & responsibilities for each discipline within the 8D process. Each discipline requires specific skills, knowledge, or authority that may not be available within a single person or department.

Therefore, it is important to assign appropriate roles & responsibilities for each discipline based on their expertise & involvement in the problem area.

Some examples of roles & responsibilities are:

By defining clear roles & responsibilities for each discipline, businesses can ensure accountability, transparency, and collaboration throughout the process.

Establish a common language & framework for communication

Another key factor for successful implementation is having a common language & framework for communication among team members & stakeholders. Communication is essential for sharing information, ideas, or feedback during the process.

However, communication can also be challenging due to different backgrounds, perspectives, or expectations among team members & stakeholders. Therefore, it is important to establish a common language & framework for communication that can facilitate understanding, alignment, and agreement throughout the process. Some examples of common language & framework are:

• Using standard terminology & definitions for the 8D process
• Implementing visual tools & templates to document & present the 8D process
• Using common metrics & criteria to measure & evaluate the 8D process
• Establishing feedback mechanisms & channels to communicate & collaborate during the 8D process

By establishing a common language & framework for communication, businesses can ensure clarity, consistency, and quality throughout the process.

Provide adequate training & support for team members

A third key factor for successful implementation is providing adequate training & support for team members who are involved in the 8D process. Team members need to have sufficient knowledge, skills, or confidence to perform their roles & responsibilities effectively. However, team members may not have prior experience or exposure to the 8D process or its tools & techniques. Therefore, it is important to provide adequate training & support for team members that can enhance their competence & capability during the process. Some examples of training & support are:

• Providing formal training sessions or workshops on the 8D process or its tools & techniques
• Offering coaching or mentoring from experts or experienced practitioners on the 8D process or its tools & techniques
• Contributing access to resources or references on the 8D process or its tools & techniques
• Maintaining feedback or recognition of team members’ performance or improvement during the 8D process

By providing adequate training & support for team members, businesses can ensure effectiveness, efficiency, and engagement throughout the process.

To illustrate the versatility and applicability of 8D problem solving across different industries and contexts, here is a hypothetical example of successful 8D problem solving:

Example: Reducing Customer Complaints in a Food Manufacturing Company

A food manufacturing company was facing a high rate of customer complaints due to foreign materials found in their products. The company used 8D problem solving to address this issue and improve product quality. Here are the steps they took within each discipline:

The company formed a cross-functional team consisting of representatives from quality assurance, production, engineering, and customer service. The team leader was the quality assurance manager who had the authority and responsibility to coordinate the activities and communicate with stakeholders.

The team defined and described the problem using data and facts from customer complaints and product inspection records. The team used the 5W2H method to clarify the aspects of the problem. The problem statement was: “In the past six months, we have received 25 customer complaints due to foreign materials such as metal shavings, plastic pieces, or wood chips found in our products.”

The team developed interim containment actions that would prevent or minimize the occurrence of foreign materials in their products until a permanent solution was found. The team identified and implemented measures such as increasing the frequency and intensity of product inspection, installing additional metal detectors and filters in the production line, and segregating and quarantining any products that were suspected or confirmed to contain foreign materials.

The team determined the root causes that were responsible for creating or allowing foreign materials to enter their products. They then used data analysis tools such as Pareto charts and fishbone diagrams to identify potential causes. Root cause analysis techniques such as 5 Whys to verify or validate the causes were also implemented.

Ultimately, they found that there were three main root causes:

• inadequate maintenance of equipment that resulted in metal shavings or plastic pieces falling off during operation;
• improper handling of raw materials that resulted in wood chips or other contaminants being mixed in during storage or transportation;
• lack of awareness or training of staff on how to prevent or detect foreign materials in products.

The team chose permanent corrective actions that would address or remove root causes permanently. The team generated multiple possible solutions using brainstorming techniques such as SCAMPER and TRIZ. They also evaluated each solution using criteria such as feasibility, effectiveness, cost, risk, or impact. Eventually, they selected the best solutions that met customer needs and expectations.

The solutions were:

• implementing a preventive maintenance program for equipment that included regular inspection, cleaning, and replacement of parts;
• establishing a quality control system for raw materials that included verification, testing, and labeling of incoming materials;
• conducting a training program for staff on how to prevent, detect, and report foreign materials in products.

The team implemented permanent corrective actions that were chosen in D5. An action plan that specified who would do what by when using tools such as Gantt charts and PDCA cycles was then developed. They then executed the action plan according to schedule using tools such as checklists and standard operating procedures.

The team prevented recurrence by ensuring that permanent corrective actions were effective and sustainable. They first verified that root causes had been eliminated using tools such as control charts and statistical process control (SPC). Next, they validated that customer requirements had been met using tools such as surveys and audits. After implementing permanent corrective actions, the rate of customer complaints due to foreign materials dropped by 90%.

Team efforts were recognized by acknowledging their contributions and achievements throughout the process. The team celebrated their success by sharing their results with stakeholders using tools such as reports and presentations. Management also appreciated their efforts by rewarding them with recognition or incentives such as certificates, gift cards, or bonuses.

Common Challenges and Best Practices in 8D Problem Solving

Despite its benefits and advantages,

8D problem solving can also pose some challenges for businesses that want to implement it effectively. Some of these challenges are:

• Resistance to change from staff or management who are used to existing processes or practices
• Lack of commitment or support from senior leaders who do not see the value or urgency of problem-solving
• Difficulty in defining or measuring problems
• Insufficient data or information to support analysis or decision making
• Conflicts or disagreements among team members or stakeholders due to different opinions or interests

To overcome these challenges and ensure successful 8D problem solving, businesses can adopt some best practices such as:

• Communicating the benefits and objectives of 8D problem solving to staff and management
• Securing the buy-in and sponsorship of senior leaders who can provide direction and resources
• Using clear and objective criteria to define and measure problems
• Collecting and analyzing relevant and reliable data or information
• Resolving conflicts or disagreements through constructive dialogue and compromise

To ensure that 8D problem-solving efforts are not wasted or forgotten, businesses need to measure the effectiveness and impact of their initiatives. Measuring the effectiveness of 8D problem-solving efforts can help businesses:

• Assess whether they have achieved their goals and expectations
• Evaluate whether they have improved their performance and customer satisfaction
• Identify areas for further improvement or optimization
• Demonstrate their value and credibility to stakeholders

To measure the effectiveness of 8D problem-solving efforts, businesses can use various methods such as:

• Key performance indicators (KPIs) that can be used to quantify the results or outcomes of 8D problem-solving initiatives. Some examples of KPIs are customer satisfaction scores, defect rates, cycle times, or cost savings.
• Data collection and analysis tools that can be used to gather and interpret data or information related to 8D problem-solving initiatives. Some examples of data collection and analysis tools are surveys, audits, control charts, or statistical process control (SPC).
• Periodic reviews and feedback mechanisms can be used to monitor and evaluate the progress and performance of 8D problem-solving initiatives. Some examples of periodic reviews and feedback mechanisms are reports, presentations, meetings, or feedback forms.

By measuring the effectiveness of 8D problem-solving efforts, businesses can ensure that they are continuously improving their quality, efficiency, and customer satisfaction.

8D Problem Solving Report

8D is a problem solving method used globally, mainly in manufacturing industry by Quality Engineers and Operations managers. The purpose of 8D problem solving method is to identify, correct and prevent problems affecting customers and operational efficiency. It is a problem solving approach similar to PDCA cycle (Plan – Do – Check – Act).

8D stands for 8 Disciplines. It is a methodology that emphasizes “No problem should be repeated but fixed permanently”.

8D Problem Solving Method originally evolved during Second World War. But it became an official methodology in 1974, when it was used by US Government for its Military Operations as ‘Military Standard 1520’. Later it was adapted and popularized by Ford Motors with slight modification in the methodology.

As the name indicates 8D has 8 disciplines that any process or operations should follow to solve the problems occurring. The outcome of 8D is a report called ‘8D Report’ that records the problems, root cause(s) and corrective and preventive actions.

The below are the D’s in 8D approach:

Figure 1: 8D Problem Solving Approach

1D  – Team Formation: The first and foremost step not only in 8D but also in any other initiative or project is Team Formation, for any initiative cannot be successful without a right team. The team selected should be committed, competent, co-ordinated, cross-functional with representation from all teams, and should be knowledgeable in 8D methodology.

2D – Problem Description: After selecting the team, our concentration should be on detailing the problem. The team should collect details about the problem, for completely understanding the depth of the problem. All details should be data and fact based.

3D – Interim Containment Actions: Once the problem is described, before heading up to problem solving, the team should fix the effect of the problem, especially on customers. It might involve actions like isolating the items affected, replacing defective parts, before it reaches the customers. This step is mainly to prevent the problem from reaching the market and customers, which might become a competitive disadvantage and reduce customer loyalty.

4D – Root Cause Analysis: After taking containment actions, the team should involve in identifying the root cause(s) for the problem. Methods and tools like 5-Why Analysis , Fishbone diagram , Pareto Analysis , 7 Old QC tools , New QC tools etc. can be used for identifying the root cause. An important point to be noted is: Whatever method is used for RCA , it should be data & fact based.

5D – Formulate Corrective Actions: After successfully arriving at the root cause, the team should formulate corrective actions to be taken to correct the problem. Tools like Brain storming, Affinity diagram etc. can be used.

6D – Validate Corrective Actions: After arriving at the corrective actions, the team should validate whether the solutions are effective. There are several tools like Accelerated life testing , simulation etc. available for this purpose. Then the solution can be implemented in the process. The solution approach from step 4-6 should be repeated until the problem is completely eliminated.

7D – Preventive Action: Identifying and implementing corrective actions is only a temporary solution that keeps the system running or is like ‘Living with the problem by taking counter measures’. The permanent solution is to identify a potential long term solution that will not allow the problem (similar problems) from occurring into the system again. Sometimes corrective action will be a costly, time being measure. Preventive action makes changes in the system, upstream or downstream processes so that the entire system is modified or aligned for ‘Problem Free’ operations.

8D – Team and Individual Recognition: Once the problem is completely solved, the team and the extra-ordinary contributors must be rewarded and recognized appropriately. This will act as a motivation factor for other employees.

These are the steps of 8D methodology. To summarize, 8D is a holistic, systematic and proven methodology for problem solving.

8D Problem Solving

When a customer issues you a corrective action you should follow the 8D problem solving methodology system. 8D stands for 8 Disciplines. The 8D approach is a complete approach to solving problems. Most customers require an 8D problem solving report for their corrective action request. The easiest approach to creating an 8D report is using 8D software.

Customer Expectations

After notification of a problem, your customer expects you to take the appropriate steps in a timely manner to resolve that problem. The quicker you address the issue, the more satisfied your customer. A thorough 8D problem solving corrective action has these additional benefits:

• It can strengthen the bond between your company and your customer.
• It can improve sales with your customer.
• It opens a new line of communication between your company and your customer.
• It prevents defects from escaping at your location.
• It corrects defects which saves you money.
• It helps guide you in future improvement efforts.

For these reasons you should follow the 8D problem solving technique.

8D Problem Solving Methodology Steps

Your 8D report documents the below steps.

• Team approach

Describe the Problem

Containment action, root cause verification.

• Implement Corrective Action
• Verify Corrective Action
• Prevent Recurrence

Congratulate the Team

Team Approach

When resolving a problem, usually the problem is not resolved by one person. Select a champion who guides the team through the 8D approach. Include process experts for the team. Select a collection of individuals who are responsible for the problem.

Give the team the authority and responsibility for making the improvements. Click here for more on the team approach .

Your 8D report should include two descriptions of the problem. The first is the description from the customer's point of view. Find this information on the customer's corrective action request.

The second description is your statement of the actual issue. Many times the customer sees one thing but in actuality it is another problem. You define the problem in your terms. For example; a customer may say the part is not polished. Your findings show the part is polished but there are finger smudges on the part.

Your statement is the D2 of the 8D process.

Your company takes action to prevent the customer from receiving additional parts with the defect. Your team reviews these areas:

• The customer’s parts in your stock
• The customer’s parts between the identified root cause area and your stock
• The customer’s parts at the identified root cause area
• The customer’s parts in shipping or during shipping
• The customer part’s in stock at the customer location

During the 8D Problem Solving methodology process your team decides upon the appropriate containment actions which depends on the nature of the problem. Document these actions in the 8D problem solving report. Your customer reviews this information and needs to feel comfortable that you contained all suspect parts.

Root cause verification may be the most difficult step of the 8D problem solving system. To help the team attack this, review the 4Ms. 4M stands for machine, material, man and method.

Was the problem caused by a machine? Machine setup? Machine tooling? Machine settings? Machine wear?

Was the problem caused by a person (man)? Training Issue? Sleep depreciation? Carelessness?

Was the problem caused by raw material? Supplier Issue? Poor traceability? Wrong material?

Was the problem caused by method? Process problem? Inaccurate procedure? Missing info in the procedure? No procedure? Wrong revision?

If necessary, use a fishbone diagram which focuses on the 4M.

After brainstorming the root cause, the team verifies the root cause. The team recreates the problem by witnessing the root cause in action. Accurate identification of the root cause is the most important step of the 8D problem solving process because it assures you put your efforts, resources and money in the right place. Problems will reoccur with poor root cause determination.

The team could encounter many root causes. Document all causes on the 8D report. Your customer will review this. Make your statements clear and understandable for your customer.

Implement the Corrective Action

After you identified the root cause, your team takes the appropriate corrective action to fix it. It is almost impossible to list all possible corrective actions as these depend on your situation.

In general, corrective action normally takes the most time and cost of the 8D problem solving methodology steps. Complete the corrective actions in a reasonable amount of time to satisfy your customer. Do not delay spending money to fix the problem. The money spent keeps your customer from walking away.

Your 8D report documents the corrective action steps, responsibilities and completed due dates. Make the actions clear, responsive, and relevant for your customer review.

Verify the Corrective Action

Your team verifies the corrective action by measuring or monitoring the results after implementing the corrective actions. Verify the customer’s problem cannot be recreated. Verification includes reviewing documentation that supports the process changes from the corrective action. Complete the verification activity by someone who did not implement the corrective action.

Let your customer know when the verification occurred. This helps the customer reset the clock for the problem.

In addition, verify the containment action and preventive action activities.

Document these verification actions on your 8D problem solving report. Include the responsible name and date on the report.

Preventive Actions

Pursue these steps to prevent the issue from reoccurring in the future. Possible preventive actions includes

• Examine this issue across other production lines and implement corrective action as necessary
• Schedule periodic training for the corrective action
• Schedule periodic audits for the problem and corrective action activities
• Include additional reviews or data collection for the problem.
• Update FMEA and quality plans

Document these preventive items on the 8D report.

It takes significant effort to resolve a problem. Upper management and the team leader need to congratulate the team. This encourages team involvement on future problems. Normally, you don't document the congratulated actions or share these with your customer.
