I was part of this type of activity on a smaller scale and the lessons
learned can be summed up by adequate requirement definitions by all
stakeholders. 
As now part of a much larger activity, the main goal I am requiring of
others is phase gate reviews and gap analysis to establish intelligent
make/buy decisions at all critical steps.

Subject: [TN] Second sources - generic components

Has anyone defined any internal standards for how to approve second
sources for "generic" components by datasheet review alone, without
running exhaustive tests on every source?
I just don't see the point in running 3 weeks of environmental and
stress tests in order to qualify a $0.002 10Kohm chip resistor second
source.  I should be able to look at a datasheet and say "yes this is
OK".  But when you make OEM products you need to justify why you are
approving it with this method, and I would like to write up some sort of
standard to cover off the bases.

I'm looking for places to start.  Thoughts?

Thanks as always, and regards,
Genny.
