Uncontrolled scope drift
Failure signal
A uncontrolled scope drift condition is reported or detected during planning.
Likely cause
The controlling record, technical state or approved specification for planning does not match the current asset or workflow.
Verification
Diff every new request against the approved deliverable list and assumptions.
Corrective action
Log the delta, owner, cost and schedule effect; approve or remove it explicitly.
Prevention
Add this verification to the planning gate, retain immutable evidence and assign one accountable owner.
