Approvals
Who approves what, when it escalates, and what happens while the approver is away.
A route is configuration
Amount thresholds, job grades and document types are rows an administrator maintains. Raising an approval limit is not a release.
Delegation and escalation
A manager’s leave does not stop the company: delegation is temporary and recorded, and a request nobody has acted on escalates by itself instead of sitting in one inbox.
Segregation of duties
The person who raises a document is not the person who approves it, and that is checked when the action is attempted rather than asserted in a policy on a wall.
