Abstract
For a couple of years, the concept of strategy has become fundamental for any type of business. According to Ansoff (1965), the practice of strategic planning is now widespread among large, medium and small firms. The strategy comes from the Greek word "stractos" which means "armed" and "agein" which means "lead". It's the art of coordinating action and the development of a policy, defined in terms of its strengths and weaknesses, taking into account the threats and opportunities. According to A.D Chandler; a strategy is to determine the objectives and the long-term fundamentals goals of an organization. In a second step, it helps in choosing the purpose, the resources and the means to achieve these goals and objectives (Chandler 1962). Strategy helps all managers take fundamental decisions about the future of a business.
