However beautiful the strategy, you should occasionally look at the results.
The term all business people are familiar with: that of competitive advantage is closely tied to a Harvard Business School professor Michael Porter. Although his two most influential books: Competitive strategy: Techniques for Analyzing Industries and Competitors and Competitive Advantage: Creating and Sustaining Superior Performance, were first published in the 1980-ies, they are still obligatory reading for managers who want to get a clue on how to gain and maintain competitive advantage. Rather than something negative, if properly managed, competition is a force that can bring out the best not only in companies but in national economies as well.
Professor Porter identified three generic strategies which determine the chances of profitability for a business either through choosing an industry that is profitable in itself or by positioning your business in a low-profitability industry in such a way as to generate superior return on your investment. These strategies are known as cost leadership (based on low cost production), differentiation (unique product qualities allow charging premium prices), and focus (on narrow market segments also known as niche markets). If chosen properly, these strategies will help a firm to leverage its strengths and protect itself against the adverse effects of the five forces that affect competitive power in an industry.
