What provides the best evidence of an organization's disaster recovery capability readiness?

Choosing the results of tests and exercises as the best evidence of an organization's disaster recovery capability readiness is sound because these activities validate the effectiveness of the disaster recovery plan (DRP) in real-world scenarios. Testing and exercises, such as tabletop exercises or full-scale drills, allow organizations to assess if they can successfully execute their recovery strategies, identify weaknesses, and confirm that personnel are familiar with their roles during an actual disaster.

While a disaster recovery plan is essential as it outlines the procedures to follow, it does not demonstrate its effectiveness without practical application. Additionally, maintaining the DRP is crucial but focuses on keeping the document updated rather than demonstrating real-world capability. Customer references may provide insights into the credibility of an alternate site provider but do not directly assess the operational readiness of the organization’s disaster recovery efforts. Thus, the actual performance of recovery exercises provides the most concrete evidence of preparedness.
