Business continuity planning defines how an organization will resume and sustain essential services after a disruption. In Information Technology, disruptions can include cyberattacks, power failures, natural disasters, hardware failures, and human error. A continuity plan documents roles, responsibilities, communication steps, alternative processes, and recovery procedures so operations can continue at an acceptable level. It typically includes priorities for restoring critical systems first, along with targets such as recovery time objective and recovery point objective. Preventive maintenance is important for reducing failures, but it is not the primary purpose of business continuity planning. Ethical policy consistency is part of governance and compliance, not continuity planning. Eliminating downtime for nonessential services is unrealistic and not a central goal; continuity focuses on maintaining or restoring critical functions, and nonessential systems may remain offline during recovery. Because the plan’s purpose is to guide an organization in restarting services and operations after an incident, the correct answer is helping define how to resume services after a disruption.
