From a single observation to a confirmed pattern.
A single operator comment on a single run is useful context. The same comment recurring across 6 runs of the same changeover is something different — it's a pattern that now has evidence behind it.
Before ProChangeover, the SMED improvement cycle for a CI engineer started with interviews: "Does anyone know why that step keeps running long?" The answer depended on who was available, what they remembered, and whether it had happened recently enough to still be front of mind.
With operator comments captured at the task level across every run, the cycle starts differently. The engineer opens the run history, filters to a task, and reads what operators wrote across the last 8 runs. If the same observation appears on 6 of them, that's not a theory — it's a case for replacing the wrench or tightening the spec.
The operators were already noticing it. Now you have a record of it.
