I have attached a sample of what we currently use for a process map (at least I hope I did it right...1st time
) It was done in Visio, but I converted to .pdf for convenience in opening.
At our last surveillance audit (ISO 13488:1996), our registrar wrote a minor AR saying that the interaction of product development processes was not defined. We had originally started the process with sales and the PO. He wanted us to start with the quoting and include the handoff to Engineering. Note: We do not do design at my company, but do develop the mfg. process.
As far as a QM, I've never heard yet that it should be kept that short, but it was suggested to us that if one of our procedures states something, try not restate it in the QM or another procedure as it gives more room for error when having to update. Our manual happens to be 22 pgs.
Hope this helps somewhat.
