Approval workflows convert policy into system behavior. Instead of relying on email chains, a document moves through defined reviewers based on module, amount, project, role or risk.
Approval levels
A simple process may require one approver. Larger transactions can require sequential Level 1, Level 2 and Level 3 approval, with different people or departments assigned to each stage.
Role vs named approver
Role-based rules are easier to maintain when staff change; named approvers are useful when accountability must be explicit. Many systems use a combination.
Exceptions and escalation
Workflows should define what happens when an approver is absent, a value exceeds a threshold or a document is rejected. Delegation and escalation prevent approvals from becoming bottlenecks.
Auditability
A good approval record captures who acted, when, what version was reviewed and whether comments were added. This creates a stronger control environment than informal messages.
