There's a version of every job that exists only because of how things were set up. A form filled in twice because two systems don't talk. An approval that waits on someone who approves everything anyway. A report built every Monday that three people receive and nobody opens. None of it is anyone's fault, and all of it is somebody's week. Take that apart and the work doesn't just get faster, it gets less annoying to do. And it gets visible. Most of these steps survive because nobody can see the whole shape of the job at once. Laid out end to end, the ones that stopped making sense years ago are obvious to everyone, including the people who've been doing them.
