Design guidance

SHOULD route by risk tier and domain expertise (e.g., database deletions to DBAs, financial approvals to controllers).
SHOULD balance workload rather than routing all requests to one person.
SHOULD escalate on decision uncertainty, exception criteria or appeal triggers rather than on superficial complexity.
SHOULD fast-track urgent or safety-critical requests past standard queue sequencing.
SHOULD match request complexity to reviewer expertise to optimize reviewer utilization.
