United States federal government continuity of operations

Continuity of Operations (COOP) is a United States federal government initiative, established and governed by U.S. Presidential Policy Directive 40 (PPD-40), to ensure that agencies can continue the performance of essential functions under a broad range of circumstances. PPD-40 specifies particular requirements for continuity plan development, including the requirement that all federal executive branch departments and agencies develop an integrated, overlapping continuity capability that ensures the continuous performance of the eight National Essential Functions (NEFs).
