No, what we're talking about is (to extend your very condescending tech support analogy) shipping the customer a new PC from the factory, and telling them to throw the old one away because it doesn't matter. It will only start to matter if they have 3 bad PCs in a row, at which time it becomes (a) a demonstrable failure and not just stray neutron rays (b) an incident which will carry a postmortum of how the organization could have prevented that failure for next time

I did start the whole thread by saying "and then I grew up," and not everyone is at the same place in their organizational maturity model. So, if you're happy with the process you have now, keep using it. I was unhappy, so I studied hard, incorporated supporting technology, and lobbied my heart out for change. Without maturity levels we'd all still be using telnet and tar based version control
