Testing Approval Delegation Coverage and Backup Authority

Research question and scope

This brief asks whether an accounts payable approval process can show who was authorized to approve a payment when the normal approver was unavailable. The unit of analysis is an approval event during a declared period, including events handled by a delegate, a backup, or an escalation path.

The scope includes invoice approvals, payment releases, and vendor master changes where the same authority model applies. It excludes HR delegation, legal signature authority, and board-level approvals unless they directly affect payables. The method focuses on evidence and design, not on whether a particular payment was strategically wise.

Define authority before testing

Collect the approval matrix, delegation policy, role descriptions, and system permission list. For each approval type, identify the primary approver, the allowed delegate, the value or risk limit, the effective dates, and the evidence required. If the documents conflict, record the conflict and resolve it with the policy owner before sampling.

Authority is not the same as system access. A person may have permission to click approve without the delegated authority to do so. The test should compare the system action with the documented authority. That comparison is the core of the review.

Build the test population

Export approval events for the period, including the approver, the delegate if recorded, the invoice or payment, the amount, the date, and the approval type. Include events that were reversed, rejected, or escalated. Those events often reveal how the process behaves under pressure.

Identify periods when the primary approver was unavailable, such as scheduled leave, travel, or a system outage. If the system does not record availability, use the delegation record and the approval timestamps to infer coverage. State the inference method and its limits. Do not treat an inference as a confirmed fact.

Run scenario tests

Test four scenarios: a planned absence with a documented delegate, an unplanned absence with a backup, a value above the delegate's limit, and a conflict of interest where the delegate is also the requester. For each scenario, trace the approval to the policy, the system record, and the supporting evidence.

A documented delegate should have a defined scope and end date. An unplanned absence may use an escalation path rather than a pre-approved delegate. A value above the limit should route to a higher authority, not be split into smaller approvals. A conflict of interest should require an independent approver. Record whether the scenario was covered and what evidence supports the conclusion.

Review the evidence trail

For each sampled event, retain the approval record, the delegation reference, the invoice or payment record, and any communication that explains the coverage. A comment that says approved by backup is not enough. The record should identify the backup, the authority basis, and the date.

Check that the delegate did not exceed the limit, that the approval was within the effective dates, and that the system permission matched the documented role. If the delegate approved after the delegation expired, the event is a finding even if the payment was otherwise valid.

Analyze coverage gaps

Report findings by approval type, department, delegate, and scenario. Look for patterns such as a backup who routinely approves above the limit or a delegation that is renewed without review. These patterns may indicate a design problem rather than an individual error.

Do not infer intent from a gap. The useful question is whether the process made the correct path clear and whether the evidence was available. A missing delegation record may be an administrative omission, a system limitation, or a deliberate workaround. Inspect before concluding.

Limitations and practical use

The method depends on the completeness of the approval log and the accuracy of the delegation records. If the organization uses email approvals, the evidence may be scattered across mailboxes. If the system overwrites the approver field, the history may be lost. State these limits rather than presenting the sample as a complete picture.

Use the findings to improve the delegation template, the approval matrix, and the system configuration. Re-test after the change. The goal is not to eliminate every exception. It is to make coverage deliberate, limited, and visible before a payment needs to move.

Method note

This brief defines an original scenario-based review method. It does not report a measured failure rate or a legal conclusion. Public internal control and identity guidance informs the design. Local application should use the organization's delegation policy, approval matrix, and system records.
