How should evidence coverage be tested during assistant access reviews?
Research on connecting each retained permission to current work, ownership, last use, and business purpose.
Headline statistic
Coverage should count permissions with complete evidence while keeping unknown, inherited, shared, and unused grants visible in the denominator.
Methodology: Research question: whether every retained permission has enough evidence to justify its scope and duration. Inventory permissions and record user, resource, level, purpose, owner, last use, authentication control, decision, and next review. This is a bounded OutsourcingAssistant.com operating study, not a causal claim, universal benchmark, or evaluation based on nationality.
Key stats
- Coverage should count permissions with complete evidence while keeping unknown, inherited, shared, and unused grants visible in the denominator.
- The eligible population, missing records, and excluded states remain explicit.
- Preparation, dependency waiting, owner decision, and execution are measured separately.
Key takeaways
- Define the operational decision before selecting the measure.
- Preserve original states and evidence for reconstruction.
- Test one documented process change, then observe a comparable period.
Define the question and eligible population
The question is whether every retained permission has enough evidence to justify its scope and duration. Declare the queue, period, included records, exclusions, and authorized decision owner before collection.
A Philippines-based assistant can maintain evidence. The accountable owner decides comparability and whether change is justified.

Build a reconstructable observation
Inventory permissions and record user, resource, level, purpose, owner, last use, authentication control, decision, and next review.
Retain prior states and source references so another reviewer can check classification without relying on memory.

Interpret within the boundary
Coverage should count permissions with complete evidence while keeping unknown, inherited, shared, and unused grants visible in the denominator.
Last-use data may be incomplete, and inactivity alone does not prove access is unnecessary for rare events or continuity.
| Item | Finding | Source note |
|---|---|---|
| Supported use | Improve the defined local operating routine | This study design |
| Unsupported use | Universal ranking, individual blame, or causal attribution | OECD measurement cautions |
Run a controlled pilot
Review two tools with different risk levels, validate a sample of retained grants, and remove access only through the authorized process.
Record the baseline, one changed rule, observation window, missing cases, and result. Stop if missing or incomparable records could reverse the conclusion.

Conclusion and limitations
The narrow conclusion is: Coverage should count permissions with complete evidence while keeping unknown, inherited, shared, and unused grants visible in the denominator. This supports local review, not a claim about every assistant or team.
Primary limitation: Last-use data may be incomplete, and inactivity alone does not prove access is unnecessary for rare events or continuity. The owner retains access, policy, personnel, customer-impact, and publication decisions.

Questions people ask
Does this create a universal benchmark?
No. It describes a defined local population and period; comparisons require compatible definitions and methods.
What work can the assistant own?
The assistant can collect observations and prepare analysis. An authorized owner decides consequential changes and public interpretation.
