Definition

The contingency lifecycle breaks down the stages of a contingency into normal operations; emergency situations; degraded modes of operation; service continuity; recovery to normal operations and (back to) normal operations.

Objective

The objective of the contingency lifecycle is to provide a common point of reference for all stakeholders to identify common stages in the progression from normal operations through the intervening stages back to normal operations again. It provides a structure for contingency planning.
