8D Problem Solving
A structured methodology for Problem Solving Analysis in 8 Disciplines.
What is the 8D Methodology?
The 8D (Eight Disciplines) methodology is a structured, team-based approach to problem-solving, designed to identify, correct, and eliminate the recurrence of complex problems. Originally used in the manufacturing industry, its effectiveness has extended it to a wide variety of sectors.
The process guides teams through eight key steps, ensuring that the root cause of the problem is addressed rather than just treating the symptoms. The disciplines are:
- D0: Plan and Prepare.
- D1: Form a Team.
- D2: Describe the Problem.
- D3: Implement Containment Actions.
- D4: Identify and Verify the Root Cause.
- D5: Develop Permanent Corrective Actions.
- D6: Implement and Validate Corrective Actions.
- D7: Prevent Recurrence.
- D8: Recognize the Team.
Brief History of 8D
The 8D methodology was developed by Ford Motor Company during the 1980s. Initially, it was known as "Team Oriented Problem Solving" (TOPS) and was officially documented in their 1987 manual of the same name. The U.S. government was one of the first to adopt it, referring to it as a military standard.
The purpose was to create a standardized method for analyzing and resolving quality and production issues. Ford found that a cross-functional team approach, following a disciplined process, was far more effective at finding robust and permanent solutions than individual efforts. The method's success at Ford led to its widespread adoption in the automotive industry and, subsequently, in the electronics, healthcare, and general manufacturing sectors, becoming a pillar of modern quality management.
How to Use This Tool
- Complete Team Information (D0): Enter the team leader's name, members, and date to document who is in charge of the analysis.
- Describe the Problem (D1): Be specific about what the problem is, where and when it occurs, and its magnitude. The more information, the better.
- Detail Containment Actions (D2): Document the immediate measures taken to protect the customer and isolate the problem while the root cause is being investigated.
- Analyze the Root Cause (D3): List potential causes and describe how they were verified to confirm the definitive root cause(s).
- Define Corrective Actions (D4): Propose solutions that will directly address the root cause.
- Verify Effectiveness (D5): Enter the data and date that demonstrate the corrective actions have solved the problem.
- Establish Preventive Actions (D6): Define what will be done to prevent this or similar problems from recurring in the future.
- Recognize the Team (D7): Document how the team's effort was recognized and the lessons learned to share the knowledge.
