Abstract
For a quarter of a century, public organizations have been preparing to manage crises. This new regulatory approach is based on a comprehensive framework comprising plans, early-warning systems, simulation exercises, and temporary organizations. Crisis management aims to reduce the uncertainty associated with the triggering event through coordination mechanisms and decision-support tools. It is also part of a reinvention of the state, which sees crises as an opportunity to reaffirm its protective missions and expand its scope of intervention into areas that were previously beyond its reach or that it had abandoned.
