8D Management & The 8D of Problem Solving

Problems are a part of life and a business is no exception. Even with the best of intentions and systems, some errors can creep in and be hard to detect. It may be nothing serious or can have serious repercussions such as reputation damage, heavy fines, product recall, property loss, and so on.

It becomes essential to identify the problem, its consequences on the one hand, and causes on the other to be able to not only resolve it for now but also ensure prevention of its recurrence.

One of the methodologies, popular amongst engineers and professionals mainly in the automotive industry but now applied across several industries is the eight disciplines (8D) model. It helps to identify, correct, and eliminate recurring problems, affecting improvement in product and process.

How to Use Root Cause Analysis to Transform Your Safety Program

8D Problem Solving Approach

The 8D is a systematic process for the introduction and improvement of quality, and elimination of problems. Here we will show you the step by step approach of the 8D problem solving tools that can make you proficient at identifying causes of problems, defining problems, and errors. Additionally, it helps identify root causes and take actions to solve and prevent identified problems in processes. So, let’s take a peep inside:

What is 8d Management? - Eight Disciplines Problem Solving Process (12)

D0: Planning and preparing for the 8D

Proper planning and preparation are always a good start before taking any action. So, you need to consider the following before forming a team:

  • Problem description
  • Timeframe for the resolution
  • The number of resources to accomplish this

What is 8d Management? - Eight Disciplines Problem Solving Process (13)

D1: Team establishment

Create a team with people who varied backgrounds and experiences which will lead to the best quality inputs and a complete solution. For the team to function smoothly, define clear roles, and responsibilities for your people, and have a team leader.

What is 8d Management? - Eight Disciplines Problem Solving Process (14)

D2: Problem description

The 8D method’s primary focus is to describe the problem appropriately and objectively such that it captures all the vital information. During this analysis, repeated 5W1H (why, what, who, where, when, and how) are required to be asked to develop a clear description.

What is 8d Management? - Eight Disciplines Problem Solving Process (15)

D3: Problem containment plan

A temporary problem containment plan is sometimes needed to minimize the impact of the problem until you develop permanent solutions. On developing the plan based on the hypothetical cases, the resources for addressing the main problem can be released. At times, new processes may be required to work around the problem until you have a permanent fix.

What is 8d Management? - Eight Disciplines Problem Solving Process (16)

D4: Root Cause Analysis (RCA)

With the problem temporarily contained, you can now turn to identify all of the root causes of the nonconformance. There are several tools to identify the actual root cause of an issue including the 5W1H to understand the problem in-depth, Fishbone diagrams to visually categorize causes, and Pareto charts to identify the vital causes.

What is 8d Management? - Eight Disciplines Problem Solving Process (17)

D5: Permanent Corrective Action

Once the root cause of the problem is determined, the team can start brainstorming permanent corrections to identify what the best long-term solution will be. Brainstorming sessions combined with tools such as affinity diagrams help organize ideas based on their relationships and determine the best course of action.

What is 8d Management? - Eight Disciplines Problem Solving Process (18)

D6: Implement and Validate the Permanent Corrective Action

Once the solution is identified, the management needs to implement and verify the corrective action using the PDCA (plan-do-check-act) approach for small-scale testing before large-scale rollout. Thus, the outcomes and corrective actions are tracked to ensure expected results. To successfully implement a permanent change, a project plan should incorporate:

  • Development of the project plan for implementation
  • Communicating the plan to all stakeholders
  • Validating improvements using measurement

What is 8d Management? - Eight Disciplines Problem Solving Process (19)

D7: Prevent Recurrence

A complete solution of problems means preventing them from occurring. Besides, preventative measures should also be implemented for corrective actions in the 8D methodology. This requires reviewing management processes, operating procedures, and 8D training manuals to ensure that best practices are followed.

At this stage, organizations should consider actions including updating process audit questions and regularly verifying them based on corrective actions to reduce risk in other processes, presenting poka-yoke or error-proofing devices to big-risk processes, and conducting red rabbit tests to see how long it takes poka-yoke devices to detect defective product.

What is 8d Management? - Eight Disciplines Problem Solving Process (20)

D8: Verification and Team Celebration

Once the problem is solved, the ultimate step is to congratulate the team. It’s important to recognize their efforts and share their success across the organization because teams require feedback to allow for satisfactory closure. This facilitates motivation and employee engagement while helping you improve quality control, execute process improvements, and aid change management as you grow.
