Isolate and verify the root cause by testing each root cause theory against the Problem Description and test data.Isolate and verify the place in the process where the effect of the root cause could have been detected and contained but was not (escape point).Today, the 8D Problem Solving Process has become a standard in many industries as problem solving or improvement process, as internal Corrective Action Request (CAR) Process or as Supplier Corrective Action Request (SCAR) Process.
D1 Establish the Team: Establish a small group of people with the process and/or product knowledge, allocated time, authority, and skills in the required technical disciplines to solve the problem and implement corrective actions.
Key Deliverables include: D2 Describe the Problem: Describe the internal or external problem by identifying “what is wrong with what” and detailing the problem in quantifiable terms.
The benefits of a systematic Problem Solving Process are obvious.
Define, verify and implement Interim Containment Action to isolate the effects of the problem from any internal and/or external Customer until Permanent Corrective (Preventive) Action are implemented.
The 8D Problem Solving Process focuses on the origin of the problem by determining root causes and establishes permanent corrective and preventive actions.
It follows a systematic eight-step process with integrated basic problem-solving tools.
With the 8D problem-solving process (or Global 8D as Ford calls it), project teams are chartered to address and solve problems by uncovering and eliminating the root cause of the problem.
Also Available: DMAIC Basics 8D Problem-Solving Training teaches learners how to solve problems in a team setting using the 8D (8Discipline) problem-solving method.

It was later improved and popularized by the Ford Motor Company in the early ‘90s.
