Hello Colleagues!
In spite of almost 30 years as a quality professional I always learn something new when I monitor these discussions. I am looking for some input on best practice for data in 8Ds and 7 step forms.
I am consultant and the automotive business is not my primary area of knowledge. I am working with a client who is automating their Corrective Action system. I am making some assumptions about best practice and I want to see if the community here agrees or am I out to lunch with my approach.
It seems to me that many layers of investigation and documentation may be developed in the course of investigating a fairly complex problem. There may be pictures, different stand alone analysis documents or test results etc. When submitting an 8D to your customer is the actual 8D form often a summary of the background investigation, containment and root cause analysis performed? Do you frequently send or are you required to send other supporting documentation that gives the details of how you arrived at your conclusions reached in the 8D form itself?
Example: a series of customer returns for failed fan assemblies. Analysis includes photos of the failure. A detailed analysis of all customer returns for like issues. A tolerance study that revealed potential assembly and fit problems at extremes. etc. I am assuming that the 8D would contain summary references rather than all the lengthy details. Example the 5 whys would each contain a couple of sentences summarizing the final answer to that step of the why. Or am I wrong and all this data would be detailed in the 8D or forwarded as supporting material? Thanks for your input. I look forward to your answers.
