Explanation
According to ISO 22301, a business continuity management system (BCMS) is a part of the organization's overall management system that establishes, implements, operates, monitors, reviews, maintains, and improves business continuity. A management system is a set of interrelated or interacting elements of an organization that establishes policies and objectives and enables the achievement of those objectives. A management system can address one or more disciplines, such as quality, environment, information security, or business continuity. Therefore, a BCMS is not limited to the IT management system, nor is it always managed by an external service provider. A BCMS is integrated with the organization's strategic direction, culture, values, and processes, and it involves the participation and commitment of all levels and functions of the organization.
