BCM 业务连续性管理（Business Continuity Management，简称BCM），是一项综合管理流程，帮助企业识别潜在的、可能影响业务系统运行的威胁，制订相应的响应框架和计划，提高企业的风险防范能力，以有效地响应非计划的业务破坏并降低不良影响。
以下是国际DR组织的官方定义，也是写入了ISO22301标准的。
Business Continuity Management (BCM)
Holistic management process that identifies potential threats to an organization and the impacts to business operations those threats, if realized, might cause, and which provides a framework for building organizational resilience with the capability of an effective response that safeguards the interests of its key stakeholders, reputation, brand and value-creating activities.
注：业务连续性管理包括组织在面临灾难时对业务活动的恢复和连续性的管理，以及为保证业务连续性的所进行的培训、演练和评审等整个方案的管理。
