Michael Porter’s 5 forces model
Porter’s 5 forces model is one of the most recognized framework for the analysis of business strategy. Porter, the guru of modern day business strategy, used theoretical frameworks derived from Industrial Organization (IO) economics to derive five forces which determine the competitive intensity and therefore attractiveness of a market. This theoretical framework, based on 5 forces, describes the attributes of an attractive industry and thus suggests when opportunities will be greater, and threats less, in these of industries.
Attractiveness in this context refers to the overall industry profitability and also reflects upon the profitability of the firm under analysis. An “unattractive” industry is one where the combination of forces acts to drive down overall profitability. A very unattractive industry would be one approaching “pure competition”, from the perspective of pure industrial economics theory.
These forces are defined as follows:
a) The threat of the entry of new competitors
b) The intensity of competitive rivalry
c) The threat of substitute products or services
d) The bargaining power of customers
e) The bargaining power of suppliers
