    I am looking for information concerning the history of 8D to add to a training course.  If anyone could provide me with information or a link to information, I would really appreciate it.
    Thanks,
    Amy

    Amy,
    One of the people involved with the creation of the 8D has posted to this forum before now – I’m ashamed to say I can’t remember her name – but if you use the search facility on previous postings I think you’ll trawl more than enough information.
    Good luck

    I found this posted some time ago…hope it helps.
    “I received Ford Motor Company’s Quality award for the development and writing of the 8D problem solving methodology. I wrote this methodology in 1986-87 upon the request of senior managment in the Powertrain engineering groups. Many of the posts have identified pieces of what the 8Ds are and how they are used. Some are not really reflective of the intent. The manual I wrote for Ford that introduced the 8D problem solving strategy was titled “Team-Oriented Problem Solving”(TOPS). It was not based on any Kepner-Tregoe(KT) material – with the exception of some material in the appendix for reference. Ford senior mangement was very unhappy with the results of KT and felt they need a statistical based approach. The material was written specifically for Ford and issues they had to address. It was never written with the intent to be used by the supply base. Hence, there are some issues as other companies try to apply the methodology. In addition, in the 1990s, Ford rewrote some of my material and retitled it “Global 8D” and put back most of the KT stuff. Hence, now you have a structure of the 8Ds trying to be supported with tools and techniques that don’t fit. Sadly, many Tier1 suppliers write some pretty awlful 8Ds and obviously don’t have the management understanding of the purpose. Many focus on the the containment actions and stop at that point – only to see the problem recur and add cost to their production centers. I am sure in most cases there is not change to the mangement structure that allowed the defect to occur in the first place. Unless the systems change, it will just be chasing one problem after another. Of course, many of the tools are used in both the 8D investigation as well as Six sigma projects. In some cases, the actual steps will be very similar. My intent with the 8Ds was to be a tempory band-aid fix to address chronic problems that have continued to recur and change the underlying management system that have allowed them to exist.”

    That’s the one.  Thanks David.
    Amy, there are other postings around this – Eileen Beachell’s name is worth a further search.
    Good luck in your hunting.

    For my numerous amount of research, I can’t find how the D’s are defined.  I know what the steps are, I just don’t know how the steps are defined as D’s…or is this a misnomer
    any help?…..

    C,
    If my memory serves me right the ‘D’ in 8D stands for Discipline – as in the 8 Disciplines you need to follow in order to kill the problem.  These Ds have been in use since the early days of TOPS (Team Oriented Problem Solving).

     GV described the 8D process somewhere in  in 2002 
    In it he says theat the 8D method of problem solving is appropriate only in “cause unknown” situataions and is not the right tool if concerns around decision making or problem prevention” Could anyone out there explain what this statement means with some practical examples.
    Thanks.

    Hi,
    GV posted in 2002 detailing the process of 8D. In it he says that the eight D  method of problem solving is approprate only in “cause unkown” situations and is not the right tool if concers center solvely around decision making or problemk prevention.
    Could anyone explain what  above statement really means preferably with a few practical examples.;
    Thanks

    Hi David,
    Some time in 2002, you wrote the following on the history   of 8D namely
    ” Hence, there are some issues as other companies try to apply the methodology. In addition, in the 1990s, Ford rewrote some of my material and retitled it “Global 8D” and put back most of the KT stuff. Hence, now you have a structure of the 8Ds trying to be supported with tools and techniques that don’t fit. Sadly, many Tier1 suppliers write some pretty awlful 8Ds and obviously don’t have the management understanding of the purpose.”
    Could u tell me which portions of KT was incorporated in Global 8D, and also what other elements are added into the Global 8D to make
