Business Continuity Planning (BCP) is an interdisciplinary concept used to create and validate a practiced logistical plan for how an organization will recover and restore partially or completely interrupted critical function(s) within a predetermined time after a disaster or extended disruption. The logistical plan is called a Business Continuity Plan.

In plain language, BCP is working out how to stay in business in the event of disaster. Incidents include local incidents like building fires, regional incidents like earthquakes, or national incidents like pandemic illnesses.

BCP may be a part of an organizational learning effort that helps reduce operational risk associated with lax information management controls. This process may be integrated with improving information security and corporate reputation risk management practices.
