Octopus Diagram, Model, or Auditing Methodology?
Icy Mountain,
Thanks for the links and description, but I would like more information on the Octopus Diagram / Model. The links did not provide information on how the Octopus Diagram was designed to be utilized. I then searched the internet, and the only information I found was a Special Reprint of The Informed Outlook (July 2002 Issue) titled "How Can You Move From QS-9000 to TS 16949:2002?" (This information was also available on the IATF site or a related site.) The article indicated that the Octopus model is an auditing methodology, which was also indicated in the links you provided. It did not describe how it was designed to be utilized. It did state that it "was discussed at the ISO/TS 16949:2002 Rollout Meeting in April, 2002 and in the IATF registrar training sessions." That was about it!
Since the COP is also utilized in the mapping of a process, I perceived that the Octopus was a tool for mapping a series of processes but did not know how it was utilized, other than the apparent listing of processes that had some sequential relationship.
As for your example, you are indicating that the legs are to be used to identify the funtions that input to the Order Review process and are the output of the process, but then when you go through the series I did not see the relationship of the Design Process. Which would lead me to the question as to how the Octopus Diagram / Model would show those processes that may be performed in parrallel or in conjunction with the overall process.
