blackholequasar,
Thanks for the input, if you are doing it successfully and your auditors like it, I think you have winner!
In my experience Turtle Diagrams have been used more like John noted, to help process owners to ensure their procedures are reasonably complete as well as a summary of the components of the process, whereas a process diagram / flow chart allows us to see the sequence of how the process is accomplished. Sort of like how a recipe lists ingredients (Turtle) and then tells us how and when to use the ingredients (flow chart)?
One thing is for sure, there is often more than one "right" way to do things, it's all about what brings value to your processes in an efficient manner. I spend considerable time on this site just trying to see how other people approach things, and I've really benefited from the advise / opinions / views / methods of others in the quality community.
