8D The 8 Disciplines Problem Solving Methodology (PDF)

This book describes the 8 Disciplines process as it is used to solve problems where Root Cause is unknown. It is to be used in conjunction with the 8D Excel template (included as a secondary document). The methods in this book conform to the de facto 8D standard used throughout industry and expected by customers and from suppliers.

8D is not a magic bullet. Improper use will lead to erroneous results. Patience and many hours of practice are required to obtain a level of proficiency. However, for newcomers to 8D, this book and the accompanying template will guide you through the process. It is possible, even expected, that Root Cause will be found and preventive measures implemented the first time the process is followed.

D0 – Preliminary Data is a conventional form used to capture high level data relevant or potentially relevant to the defect.

D1 – Team Selection is premised on the belief that correct team formation is critical to finding Root Cause and that mistakes made here will permeate throughout the entire process.

D2 – Problem Definition uses the IS/ISNOT format to define the problem.

D3 – Containment is a process that involves multiple parties, varying commercial commitments and multidisciplinary collaboration. It is facilitated by a Risk Assessment, Communication Plan, Containment Recommendation & Containment Action Plan.

D4 – Root Cause is expanded well beyond the traditional 8D tool set of 5 Why's and Fishbone Diagram by introducing 18 Root Cause tools. This expansive set equips the practioner for every conceivable defect scenario.

D5 – Corrective Action. 35 different techniques for identifying the appropriate Corrective Action are covered.

D6 – Implementation also includes Root Cause verification. Learn the 9 methods for validating Root Cause.

D7 – Problem Prevention includes a look at the Control Continuum and 36 specific actions that can be taken to prevent problem recurrence.

D8 – Congratulating the team is often overlooked. Learn how to meaningfully reward the team for their efforts.

This book of nearly 60 pages is one of the most comprehensive reviews of 8D available. It is excellent for independent study or classroom training.
