Think of BCDR (Business Continuity & Disaster Recovery) as your emergency kit. It is a specific set of tactical plans to restore IT and operations immediately after a crisis to get back to normal.
Business Resilience is your immune system. It is a broader, holistic strategy that includes BCDR but extends to financial health, organizational culture and leadership. BCDR targets recovering from a specific disruptive event, like a fire or hack. Resilience focuses on adapting to any change, like a market crash or new competitor, so the business can evolve and thrive long-term.
