Oh fuck off !!!!
Surely, *surely* SURELY there is an A4 list of go/no-go sanity checkpoints for EVERY SINGLE RELEASE.
As a developer, and a development manager, it would have been the first thing I would have wanted from my dev team - even before the first line of code was written.
But then that's years of experience, and knowing that if you don't, then your latest release *will* crash on startup in front of your most valued customer.
