In the section Part 2, 8.3.6, you suggested that if the design is simple, we could use a single document to captures all design related information in one place, namely the “Design Control Form”, DCF. I really think that this would be a great idea, as the product in my company is really simple.
Currently we have a bunch of design information for each product, and use ECN to control subsequent design change. There are much information inside our ECN, and it looks fine to me actually. Information like change method (running or immediate change), inventory control for obsoleted material, updated drawings version, BOM revision and so on is all around in the ECN. should I dump the entire ECN content into the DCF? or adopting DCF with design change information being exlcuded?
