This document introduces concepts related to crisis communications and management. It defines a crisis as a major negative occurrence that interrupts normal business and can threaten an organization's existence. Crisis management involves strategic planning to control risks and uncertainties, while crisis communications is dialogue with stakeholders before, during, and after a crisis to minimize reputational damage. The stages of a crisis are defined as detection, prevention/preparation, containment, recovery, and learning. Effective crisis management includes communications that can alleviate or eliminate the crisis and sometimes bring an organization a more positive reputation.
