A route, unit or plate change can affect validated operating conditions; review it before starting.
Decision table
- Item changed and reason
- Product or route affected
- Risk and evidence needed
- Owner and rollback
Protect the condition of validity
Purchasing approval alone does not preserve thermal evidence. Record product, process and monitoring effects.
Method for the protocol
Assign the trial, document update and transition date to an owner. Define rollback conditions before implementation.
For urgent changes, log scope, authority, closure.
