A predetermined set of instructions or procedures that describe how an organization's mission essential functions will be sustained within 12 hours and for up to 30 days as a result of a disaster…

A Continuity of Operations Plan (COOP) focuses on maintaining the essential functions of an organization during and after a disruption, typically for an intermediate period (like 30 days) until full recovery. It ensures that critical business processes can continue with minimal interruption, often emphasizing relocation or alternate site operations.

An Operations Plan is a general plan for day-to-day activities, not specifically for disaster recovery or continuity.

A Disaster Recovery Plan (DRP) typically focuses on the recovery of IT systems and infrastructure to a functional state, rather than the broader continuity of all mission-essential business functions for an extended period.

An Incident Response Plan (IRP) focuses on immediate actions to respond to and mitigate security incidents, not the sustained operations of essential functions over days or weeks.
