Crisis management involves dealing with unpredictable threats to an organization. It consists of methods to respond to crises, metrics to define crisis scenarios, and communication during emergencies. A crisis threatens an organization and requires a timely response and open communication. Different types of crises include natural disasters, malevolence, and organizational misdeeds. Successful crisis management requires planning beforehand and understanding how to handle each phase of a crisis.
