Today, countless new niche and specialty market opportunities are emerging as the era of mass marketing comes to an end. George S. Day argues persuasively that old ways of competing and much of the conventional wisdom about organizations are being overturned by a convergence of forces: mass markets are fragmenting into narrow segments that are themselves becoming global markets; information technologies are blurring the boundaries between markets and organizations while accelerating the pace of decisions; technological change continues to shrink product life cycles while customers are demanding ever higher levels of responsiveness and quality.

A powerful vision is a shared intention that creates a winning atmosphere throughout the organization. By focusing attention on a desired leadership position, measuring progress against that achievement, and continually seeking new ways to gain competitive advantage by serving customers better, the actions and aspiration of
