Porter 5 Forces
There is continuing interest in the study of the forces that impact on an organisation, particularly those that can be harnessed to provide competitive advantage. The ideas and models which emerged during the period from 1979 to the mid-1980s (Porter, 1998) were based on the idea that competitive advantage came from the ability to earn a return on investment that was better than the average for the industry sector (Thurlby, 1998).
As Porter's 5 Forces analysis deals with factors outside an industry that influence the nature of competition within it, the forces inside the industry (microenvironment) that influence the way in which firms compete, and so the industry’s likely profitability is conducted in Porter’s five forces model. A business has to understand the dynamics of its industries and markets in order to compete effectively in the marketplace. Porter (1980a) defined the forces which drive competition, contending that the competitive environment is created by the interaction of five different forces acting on a business. In addition to rivalry among existing firms and the threat of new entrants into the market, there are also the forces of supplier power, the power of the buyers, and the threat of substitute products or services. Porter suggested that the intensity of competition is determined by the relative strengths of these forces.
Five Forces Analysis helps the marketer to contrast a competitive environment. It has similarities with other tools for environmental audit, such as PEST analysis, but tends to focus on the single, stand alone, business or SBU (Strategic Business Unit) rather than a single product or range of products. For example, Dell would analyse the market for Business Computers i.e. one of its SBUs.
Five forces analsysis looks at five key areas namely the threat of entry, the power of buyers, the power of suppliers, the threat of substitutes, and competitive rivalry.
The threat of entry.
