Explanation : The Five Forces model developed by Michael E. Porter has been the most commonly used analytical tool for gramining competitive environment. According to this model, the intensity of competition in an industry depends on five basic forces. These five forces are:
1. The threat of new entrants
2. The intensity of rivalry among industry competitors
3. Bargaining power of buyers
4. Bargaining power of suppliers
5. The threat of substitute products and services.
Each of these forces affects a firm’s ability to compete in a given market. Together, they determine the profit potential for a particular industry. To Wnderstand industry competition and profitability, one must analyze the industry’s underlying structure in terms of the five forces, as shown in the figure below.
