In today's dynamic business environment, strategy too must become dynamic. The essence of strategy is not the structure of a company's products but the dynamics of its behavior. To succeed, a company must weave its key business processes into hard-to-imitate strategic capabilities that distinguish it from its competitors. A capability is a set of business processes understood strategically. While such capabilities are collective and cross-functional, they must be built and managed by the CEO. Uses examples from Wal-Mart.
