who is responsible for maintaining the business continuity plan
The management of business continuity falls largely within the sphere of quality management and risk management, with some cross-over into related fields such as governance, information security and compliance. Risk management is an important tool for business continuity as it provides a structured way to identify the sources of business disruption and assess their probability and harm. It is expected that all business functions, operations, supplies, systems, relationships, etc. that are critically important to achieve the organization's operational objectives are analyzed and included in the business continuity plan. Business Impact Analysis is the generally accepted risk management term for the process of determining the relative importance or criticality of those elements, and in turn drives the priorities, planning, preparations and other business continuity management activities.
