Answer
Business Continuity Planning (BCP) relates to the detailed plan prepared to make sure the business processes and systems continue operating in the event of a disaster. This creates a detailed plan along with recovery procedures, roles, responsibilities and stepwise plan of action to restore the systems and services in the event of a natural or man-made disaster affecting normal system operation.
A well-crafted BCP is important because it can act as a guiding document for the management and IT team of the organization to restore the services, recover data and in the event of that taking longer time, to follow an alternate course of action so that business processes continue to function. This tells how to recover services, restore data and whom to involve or resort to in case of an emergency. Not having this plan can lead to chaos, data loss, mismanagement and loss of credibility in the face of a major outage caused by a disaster or any other circumstance.
