What is the Meaning & Definition of contingency plan

A contingency plan is a plan preventive, predictive and reactive type. It has a strategic and operative structure that helps to control an emergency situation and to minimize its negative consequences (stop time, etc.). The contingency plan offers a whole range of alternative procedures to the normal functioning of an organization, when one of his usual duties is affected by internal or external contingency.
This class of plan therefore seeks to ensure the continuity of the functioning of the Organization against any eventuality that may be material or personal. A contingency plan involves four basic steps: assessment, planning, evidence of sustainability, and execution.
Experts recommend plan even before that it is necessary; that is, until an accident occurs. In addition, a contingency plan must be dynamic and must include alternatives to new impacts that can occur over time. For this reason, it must be updated and reviewed periodically.
A contingency plan should also establish some strategic objectives and a plan of action to respond to certain challenges.
In computing, a contingency plan is an alternative program that allows a company to recover a computer disaster and mend its operations in a timely manner. These plans also bear the name of DRP's English Disaster Recovery Plan (or business resumption plan).
A DRP program includes a support plan (which is done first and foremost threat), an emergency plan (which is developed during a threat) and a recovery plan (which includes measures to be applied once the threat is controlled).
