What is the best definition of COOP in emergency planning?

The best definition of COOP, which stands for Continuity of Operations Plan, is that it is part of an employer emergency plan. COOP refers to the strategies and procedures that organizations put in place to ensure that essential functions continue during and after a significant disruption, such as a natural disaster or other emergencies. This type of planning is critical for maintaining business operations, safeguarding personnel, and ensuring that critical services are delivered, particularly in the face of unexpected events.

The COOP focuses on the ability of an organization to sustain its operations and provide essential services under all circumstances, which aligns well with the understanding of it being integral to an employer's overarching emergency plan.
