True competitive advantages are harder to find and maintain than people realize. The odds are best in tightly drawn markets, not big, sprawling ones.

Frequently it's just another way of saying, "This is important" The reality is that there are only a few situations in which companies' strategies affect outcomes. Such situations are, however, worth trying to create since the alternative, achieving superior efficiency, is a more demanding route to success, and a more impermanent one.

A firm that has privileged access to customers or suppliers or that benefits from some other competitive advantage will have few of these agents to contend with. Potential competitors without an advantage, if they have their wits about them, will choose to stay away. Thus, competitive advantages are actually barriers to entry. Indeed, the two are, for all intents and purposes, indistinguishable.
