Where it usually breaks
And how to keep it from happening.
- Erased history. Do not delete the original acceptance or decision to explain a later equipment change. Retain the evidence that led to the executed scope.
- Wrong correction path. Establish whether work has already executed before deciding how to handle the customer's change.
- Assumed success. An unresolved operation needs corroborating evidence. A repeated request or an optimistic note does not establish completion.
