In many situations, speed is required in planning and implementation to achieve success. Contingency planning can facilitate crisis action planning, rapid execution, and replanning. To facilitate rapid planning and implementation, planning processes must be formalized and well understood. Also, to facilitate rapid response and execution some slack resources must be maintained. In general, the speed or pace of planning and execution must be deliberate and measured. Planning is usually ineffective when it is conducted hurriedly and at a frenetic pace. Frenzy means the planning process and analyses are not controlled by logic and reason, but rather the process is controlled by anger, rage or other violent emotion.
