if my memory serve me right, the design authority is the program office who signed off the whole design package (that including SOW, contractual agreement, etc.etc.). Program Mgr that oversee the whole design/reliability/compliances/legal issues (usually a company/or group of companies). I remember many moons ago, our eng team got an request to change part to save money from one of the partners, the request were sent to program office and forward to engineering dept for assessment (temperature range issues)... it was hard fought until the requester realize it need put up full qual cost for the unit (since the change was not "equivalent or better" and key components/ material change, including PWB, etc. those were consider as major change... besides, the new temp range proposed "eat" into the design margin... It was put into the rest once for all - at least once in my all work life in that company... many long distance conf call... the old days, internet was not that powerful). Prog Mgr usually very careful about changes, since it require his signature and his head was on line)... IMHO. Good luck and have a lots of mountain dew before you start "authority" process - a major challenges to keep good relationship with chaps on the other end... jk On Nov 29, 2018, at 8:48 AM, Douglas Pauls wrote: > Good afternoon all, > > A question for you.
