When you need it
Use this register when a technical audit or condition review must show which systems, assets, questions, and samples were actually examined, especially where access limitations prevent complete inspection or evidence coverage.

How to use this template
What it helps you decide
It separates planned coverage from work performed and findings reached, helping readers understand how far an audit conclusion can reasonably extend and where specialist follow-up or additional sampling remains necessary.
How to complete it
- Record Coverage ID, System / asset, and Audit question / criterion, then define Population / sampling basis and Planned sample / method before examining evidence.
- Populate Actual sample / work performed and Access / evidence limitations honestly, linking Evidence references to the specific systems and audit questions actually reviewed.
- Set Coverage status and Assessment result separately, assigning Specialist / follow-up where missing access, uncertain evidence, or technical complexity limits the conclusion that can be drawn.
Who prepares and reviews it
The audit lead normally maintains coverage with discipline specialists, inspectors, and asset-data contributors. A competent reviewer checks whether the sample supports the conclusion, while the commissioning organization determines any further investigation within the agreed audit scope.
A mistake to avoid
Marking a system satisfactory when only its document list was checked confuses evidence availability with technical assessment and can overstate the audit's actual coverage.
Illustrative example
Illustrative example: an industrial-building audit plans to inspect roof connections but several bays are inaccessible during production. The register records the accessible sample, photographs, and excluded bays. The report limits its conclusion accordingly and recommends targeted access for the unexamined connections before a broader assurance decision.
