Third Party Review
Define how vendors, services, and external tools are reviewed before use.
Purpose
Third-party review should clarify business need, data exposure, integration scope, operational dependency, and accountability before the service becomes embedded in work.
Policy shape
| Rule | State the expected behavior in direct language. |
|---|---|
| Reason | Explain the operating risk or obligation behind the rule. |
| Owner | Name who maintains the policy and decides exceptions. |
| Evidence | Define what proves the policy is being followed. |
| Review | Set a review cadence and update trigger. |
When to use
- When the work repeats often enough that memory is no longer reliable.
- When more than one person may request, perform, review, or inherit the work.
- When risk, approval, evidence, or handoff needs to be visible later.
Common failure modes
- Approval focuses on price while ignoring support burden.
- Integration creates hidden access.
- Exit conditions are not documented.
Review guidance
Review this page after a material incident, after a role or system change, and on a normal cadence appropriate to its risk. During review, check whether the owner is still correct, whether inputs are still complete, whether the output is still useful, and whether related pages need updates.
