Porters Five Forces:
The Five forces is a model created by Michael E. Porter of Harvard Business in 1979. The
five forces is a framework for an industry analysis and the business strategy development.
This framework uses concepts developed within the industrial organization economics.
The forces determine the competitive intensity and attractiveness of a market.
These forces affect the company and their ability to serve its customers and produce a
profit. This means that a change in such forces will require the company to reassess their
efforts to shift with the market. These forces also help a company in making a qualitative
evaluation of the firms strategic position. A strategic manager may use this model to better
understand the industry in which the firm operates, in order to create a greater competitive
advantage.
In an industry with two or more competitors, competitive intensity increases. As this
increases the average industry return falls. When the bargaining power of buyers and
suppliers is high, the threat from new entrants and substitute products is high thus creating
an intense rivalry among firms. Within this the five forces are created, as illustrated in
Figure 1.
In each of these forces there are circumstances that increase the power of each of the
forces. These can be used as tools by a strategist to create an edge over competition and
can be used to boost a companys profitability and take away from other competitors in the
industry. These circumstances will be further discussed further in the paper and can be
seen in figure 2.
Supplier Power:
Supplies in an industry are raw materials, labor, machinery, services and capital. These are
all necessary inputs to the firms production process. These materials are all supplied by
different interest groups within the industry.
The strength of suppliers affects the industrys profit potential. Suppliers have the power
over companies in an industry by threatening to raise prices or reduce the quality of
purchases goods and services. They can also exert an influence on the producing industry,
such as selling raw materials at a high price to capture some of the industries profits
(Porter, 27-28). Figure 3 and 4 show when a supplier is powerful and weak as well as
