> A system that passes it's integration test 100 times isn't necessarily particularly impressive in terms of reliability.

So extending your own metaphor and using 100 as the number of missions, the integration test failed 2% of the time.

A 2% failure rate isn't impressive, but I'm fine not crediting any of the shuttle issues to software. My only point is that 100 instance of use for purpose isn't enough, to my mind, to argue that a piece of software is exceptionally reliable.
