I'd say that the extra moving parts are there in most cases not because someone wanted to "feel smart" (not that it doesn't happen), but to make the pre-existing moving parts do something that they weren't originally supposed to do, because nobody understands how those pre-existing parts work well enough to re-engineer them properly on the schedule that they are given. We are an industry that builds bridges out of matchsticks, duck tape, and glue, and many of our processes are basically about how to make the result of that "good enough".
