This document discusses the Area Business Continuity Management (Area BCM) initiative, which aims to develop a scalable cross-sector coordination framework for disaster management and business continuity. The Great East Japan Earthquake showed that individual business continuity plans were insufficient due to disruptions of common resources like energy and transportation. Area BCM establishes coordination between private businesses, public sectors, and communities to maintain critical external resources and infrastructure. It involves understanding risks and impacts, developing area-wide business continuity plans, implementing measures across prevention/mitigation, preparedness/response and recovery, and continually monitoring and improving the system. Case studies demonstrate how Area BCM coordinates stakeholders to strengthen resilience.
