# cp-4 - \[catalog\] Contingency Plan Testing

## Control Statement

- \[a\] Test the contingency plan for the system frequency using the following tests to determine the effectiveness of the plan and the readiness to execute the plan: organization-defined tests.

- \[b\] Review the contingency plan test results; and

- \[c\] Initiate corrective actions, if needed.

## Control guidance

Methods for testing contingency plans to determine the effectiveness of the plans and identify potential weaknesses include checklists, walk-through and tabletop exercises, simulations (parallel or full interrupt), and comprehensive exercises. Organizations conduct testing based on the requirements in contingency plans and include a determination of the effects on organizational operations, assets, and individuals due to contingency operations. Organizations have flexibility and discretion in the breadth, depth, and timelines of corrective actions.

## Control assessment-objective

the contingency plan for the system is tested frequency;
tests are used to determine the effectiveness of the plan;
tests are used to determine the readiness to execute the plan;
the contingency plan test results are reviewed;
corrective actions are initiated, if needed.
