A fresh beginning works better when the old source of confusion has been named.

Starting again feels clean, which is exactly why the old fault so often travels with it. The team reorganizes, the couple moves house, the system gets rebuilt, and within a few months the same misunderstanding surfaces, because it was never described, only left behind. New arrangements inherit unexamined ones.

Before you restart anything, write one honest paragraph about what caused the trouble last time. Say it aloud to whoever else is involved, without assigning blame. Then design the new version specifically against that.
