Porter's Five-Forces Analysis of Market Structure

Lack of Differentiation or Low Switching Costs

When buyers find a differentiated product that satisfies their needs, they frequently purchase the product loyally over time. Industries with many companies that have successfully differentiated their products have less rivalry, resulting in lower competition for individual firms. However, when buyers view products as commodities (as products with few differentiated features or capabilities), rivalry intensifies. In these instances, buyers' purchasing decisions are based primarily on price and, to a lesser degree, service. Film for cameras is an example of a commodity. Thus, the competition between Fuji and Kodak is expected to be strong.

The effect of switching costs is identical to that described for differentiated products. The lower the buyers' switching costs, the easier it is for competitors to attract buyers through pricing and service offerings. High switching costs, however, at least partially insulate the firm from rivals' efforts to attract customers. Interestingly, the switching costs – such as pilot and mechanic training – are high in aircraft purchases, yet, the rivalry between Boeing and Airbus remains intense because the stakes for both are extremely high.
