The Power of 8D: Solving Problems, Six Sigma Style

Last Updated on 13 September 2023

As we embark on our journey to master Lean Six Sigma strategies, we cannot overlook the strength accruing from the eight disciplines, fondly referred to as 8D. With the power to guide us through the seemingly arduous paths of problem-solving, 8D enhances our abilities to evaluate, address, and eradicate problems for good.

Introduction to 8D

The 8D method is a systematic, team-based approach to identifying, analyzing, and rectifying problems that hinder process improvement. Although initially popularized as a methodology in the automotive industry, 8D has transformed into a ubiquitous problem-solving tool utilized across a myriad of industries.

The Eight Disciplines of 8D

1. D1: Build the Team: Form a team of individuals with the necessary skills, knowledge, and time to resolve the problem.
2. D2: Describe the Problem: Clearly articulate the issue at hand with pertinent data and information.
3. D3: Implement and Verify Interim Containment Actions: Establish temporary measures to curtail the problem’s effect until a permanent solution is implemented.
4. D4: Determine, Identify, and Verify Root Causes: Utilize various tools (Fishbone Diagram, Five Whys, Pareto Analysis) to trace and confirm the core cause of the problem.
5. D5: Choose and Verify Corrective Actions: Select the most viable solutions to the root problem and test these to confirm their effectiveness.
6. D6: Implement Permanent Corrective Actions: Embed the verified solutions as standard processes to prevent recurrence of the problem.
7. D7: Prevent Recurrence: Modify management systems, operating systems, practices, and procedures to prevent recurrence of this and all similar problems.
8. D8: Congratulate Your Team: Recognize the contributions and efforts of your team and celebrate the success of overcoming the problem.

Why 8D Matters to Six Sigma Ninjas?

As Six Sigma practitioners, we strive to ensure quality, improve processes, and reduce variations. With 8D, we embrace a structured, effective methodology that aids us in achieving these goals. The 8D strategy ensures a systematic approach to permanent problem resolution, making it a powerful tool in our Six Sigma arsenal.
