As part of my daily routine, feigning surprise at the fact that, given a tree of decisions, I'm only permitted to code for the ones that make money, simply to find that "Quality Testing" reveals the 500 other permutations will inevitably result in thrown exceptions with hideous, glaring error messages.
"WHOOPS."
When I was in a CMMI training class 10 or more years ago, the instructor we had said basically that much. By instantiating a process, it takes the mental weight of knowing (or checking) if everything is correct.
No one builds cars that way - why should we build anything that way. The processes should catch the inevitable human errors.
