According to Requirement R3.1, how many days after a recovery plan test must lessons learned be documented?

Requirement R3.1 of the NERC Critical Infrastructure Protection (CIP) v7 Standards specifies that lessons learned from a recovery plan test must be documented within 90 calendar days after the test. This timeframe is established to ensure that organizations promptly assess the effectiveness of their recovery plans and incorporate any insights gained to enhance future performance and resilience.

Documenting lessons learned within this period is critical for maintaining operational readiness and continuously improving recovery strategies. An extended timeframe, such as 120 calendar days or longer, would delay the incorporation of valuable insights, potentially leading to gaps in preparedness. Therefore, the requirement emphasizes a structured and timely review process, and documenting lessons learned within 90 days strikes an appropriate balance between thorough analysis and operational urgency.
