INTRODUCTION TO 8D PROBLEM SOLVING & REPORT WRITING(3LEGS 5WHY METHODOLOGY)

INTRODUCTION FOR INTRODUCTION TO 8D PROBLEM SOLVING & REPORT WRITING (3LEGS 5WHY METHODOLOGY)

The 8D (Eight Disciplines) Problem Solving methodology is a proven, structured approach for resolving complex problems and preventing their recurrence. Originally developed by Ford Motor Company, 8D is now a globally recognized standard in manufacturing, assembly, and service industries.

This team-oriented methodology helps organizations:

• Identify the root cause of critical issues
• Implement short-term containment actions
• Develop permanent corrective actions to prevent recurrence

The strength of the 8D method lies in its systematic structure and use of varied analytical tools. It combines best practices from multiple quality and reliability techniques, making it a comprehensive solution for continuous improvement and customer satisfaction.

LEARNING OBJECTIVES

By the end of the training, participants will be able to:

• Apply each step of the 8D problem-solving process
• Link 8D to FMEA, APQP, and Product Development Processes
• Lead and participate effectively in Cross-Functional Teams (CFTs)
• Define clear and accurate problem statements and root causes
• Utilize tools such as 3-Legged 5 Why, Fishbone Diagrams, and Affinity Diagrams
• Implement Interim Containment Actions and Permanent Corrective Actions
• Manage and store 8D reports as part of the organization’s Lessons Learned
• Write clear and concise 8D reports for various stakeholders

LEARNING OUTCOMES

Participants will be equipped to:

• Confidently perform all steps of the 8D methodology in real work scenarios
• Identify and verify root causes using structured analysis
• Write and review clear, structured 8D reports tailored to technical and managerial audiences
• Facilitate 8D problem-solving teams and implement corrective actions
• Use analytical tools like 3-Legged 5 Why, Ishikawa Diagram, and Affinity Diagram effectively
• Develop robust documentation and capture lessons learned for future prevention
