Deciding on the structure and composition of a crisis team on the day of a crisis simply does not work. Effective performance during a crisis relies very much on team members' prior understanding of their roles and responsibilities in responding to an escalating event.
Organisations that know what to do, who is going to do it, and in what sequence, are more effective during a crisis. A prepared organisation can respond faster and better with reduced decision making time. Cooperation between team members enhances effectiveness and this experience through pre-training, discussion and planning will increase response.
A crisis team that is used to working together under clear leadership moves into their operational function with a more positive approach particularly in chaotic situations. Shared knowledge of the team organisation produces a capability far greater than the sum of individual members.
