Based on what MC was asking, i would define failed as not making it to market.
Looking around the office here, and working on a program that was managed into oblivion, I have an aweful track record. In 3 years, I have worked on 4 major programs and all of them failed. 3 failed to go to market, and the last was a colossal market failure.
I am looking at a collegue of mine who has worked on 7 programs in the past 5 years and all of them have tanked in one way or another.
It still astounds me that mgmt will invest as much money as they do in a program and cancel it last minute.
