Michael E Porter and the Five Forces that shape industry

The first time I heard of Michael E Porter's Five Forces Competitive Framework was when I was pursuing my marketing degree program years ago and since then, it's application has helped me tremendously to chart my business directions strategically insofar as competiting with like-minded players in the industry.

In essence, the job of the strategist is to understand and cope with competition. Often, however, managers define competition too narrowly, as if it occurred only among today’s direct competitors. Yet competition for profits goes beyond established industry rivals to include four other competitive forces as well: customers, suppliers, potential entrants, and substitute products. The extended rivalry that results from all five forces defines an industry’s structure and shapes the nature of competitive interaction within an industry.

As different from one another as industries might appear on the surface, the underlying drivers of profitability are the same. The global auto industry, for instance, appears to have nothing in common with the worldwide market for art masterpieces or the heavily regulated health-care delivery industry in Europe. But to understand industry competition and profitability in each of those three cases, one must analyze the industry’s underlying structure in terms of the five forces.
