I am looking for some examples of completed "Turtle Diagrams" Any help out there
Hi, Reggie! Welcome to the Cove!
One thing you might benefit from (I suspect your company is essentially a "boutique" operation applying your electric heating technology to a variety of products as customers come along)
is a basic grounding in a few of the so-called "quality tools" a lot of the old-timers in the quality business take for granted.
(Failure Mode and Evaluation Analysis) - this is essentially a process for "sitting down and thinking" about the possible things that could go wrong in manufacturing and/or using a product, then devising "work arounds" to avoid them happening.
(sometimes referred to by the Japanese term Poka Yoke or the more colloquial "goof proofing.") - a process for eliminating opportunities for error. Take a look at this website for a good background (John Grout's Poka-Yoke Page
"Root cause investigation"
- often, amateurs make the mistake of not digging deep enough to discover the true underlying cause of nonconformances or excessive variation in a process. The treatment of root cause investigation given in this Department of Energy document can be heavy going, but it is free and if you get hung up on anything, we here at the Cove will always be available to help you over the tough spots (nst1004.pdf
I happen to think you and your organization need a little grounding in the basics of getting your processes working smoothly as a prelude to developing the statistics to tell you "how smoothly" you are running.
My basic philosophy has always been that an organization needs to be working toward a common purpose (delivery of quality products to a customer at a profit)
and that the introduction of statistics into the mix is a helpful aid in pinpointing areas for improvement. In the case you have shown in another thread, there is nothing subtle about the fact one of the products has a big spike in nonconformance (failures) and investigation into the root cause of that will give your organization a knowledge base for preventing similar spikes in other products as you run through a FMEA prior to beginning production on each new product.
Turtle diagrams (and "octopus" ones, as well) are often associated with the automotive industry. If you are really interested, we can arrange for you to get a copy of ISO/TS 16949:2002 IMPLEMENTATION GUIDE, a 207 page pdf file, which includes a brief discourse on integrating turtles and octopuses (octopi?) with the manufacturing process. They will help in both
- problem solving after a problem is discovered
- preventive planning to prevent nonconformances and problems before they can ever occur.
