This paper tries to shed light on the concept of the crisis and the crisis management. This interest comes from the importance of the crisis management discipline as a way to reduce the negative spillovers of the crisis and an art to create a permanent custom to live with crisis. In this context, the concept of the crisis will change from a pejorative concept inspiring damage and destruction to an economic and managerial one. The latter allows us to treat it as a business phenomenon and then the economic laws are applied to find out the resolution and take advantage from it. Keywords: Crisis – Crisis Management – Spillover - Metho
