WOW,I'm happy to have rised such discussion,I agree again with Sidney . Of course we have a process before the Design process ,described on suitable procedure, which is called R&D :its output is the input for the design and indrustrialization process.
Let me "comment" step by step the standard 7.3:
7.3.1 ...duringthe design anddevelpment the orhanization shall detrmine:
-
the design and dev phase when an idea is developed one can know the start of the process but not when it will be completed and many times the results are not the expected one but even better for another different application ( remeber that the penicillin was descovered by chance, and many times some of our products , developed from one idea,were sucessfulyy used in other complete different application) . Some time it also take 2 years or more for the starting of the prototype assembly.
7.3.2 design inputs:
-
functional andperforfance requirement: Have you never dealed with the R&D labs of the big group like Philips,Osram, Hitachi Toshiba ect? during their starting study they don't know what they really want, the product is jointly researched and tailor made on the project. Than no requirements till the beta prototype ( the one close to the final configuration) is produced after many alpha trials.
....
requirement shall be complete, unambiguous and not in conflict... At the starting of the idea development, there are so many changes in the configuration ( even 3-4 pre-pototype per week ) that it is impossible to have complete and unambigous requirements.
Thanks and up with the democracy of course.. but a standard should be a little bit more clear in defining some important aspects like the ones we are discussing about, otherwise during the audit there will be lways some confusions or misunderstanding.
