This unit describes the skills and knowledge required to perform in a leadership role during phases of a crisis. It applies to roles assigned with accountability and/or responsibility for crisis mitigation, preparedness and response and recovery within communities and/or organisations. A crisis is defined as an event of significant disruption having a broad effect on relationships among communities and/or organisations. It is characterised by high levels of adversity, ambiguity, uncertainty, opportunity and change. Leaders in the preparation, mitigation and recovery phases of crises have key roles in influencing and supporting stakeholders and communities. They need to independently make sense of uncertain situations, creatively seek solutions and apply judgment and decision making in highly pressurised environments.Emergency service leaders typically work autonomously within collegiate environments that require the ability to build and develop relationships and partnerships with a broad range of formal and informal groups. Emergency service leadership roles are complex requiring the individual to make ethical decisions in variable, evolving and dynamic circumstances.No licensing, legislative or certification requirements apply to the unit at the time of publication.
