“The essential complement to the path-breaking book Competitive Strategy, Michael E. Porter’s Competitive Advantage explores the underpinnings of competitive advantage in the individual firm.

 Competitive Advantage introduces a whole new way of understanding what a firm does. Porter’s groundbreaking concept of the value chain disaggregates a company into “activities,” or the discrete functions or processes that represent the elemental building blocks of competitive advantage.”

Context: The competition between human beings destroys with cold and diabolic brutality.... Under the pressure of this competitive fury we have not only forgotten what is useful to humanity as a whole, but even that which is good and advantageous to the individual.... One asks, which is more damaging to modern humanity: the thirst for money or consuming haste... in either case, fear plays a very important role: the fear of being overtaken by one's competitors, the fear of becoming poor, the fear of making wrong decisions or the fear of not being up to snuff.
