Michael Porter and Sustainable Competitive Advantage Just because a company is the market leader now, doesn't mean it will be forever. A company must create clear goals, strategies, and operations to build sustainable competitive advantage. The corporate culture and values of the employees must be in alignment with those goals.

Porter outlined the three primary ways companies achieve a sustainable advantage. They are cost leadership, differentiation, and focus.
