Drucker argues that in the post-capitalist society, managers must learn to negotiate a new environment with a different set of work rules and career expectations. Companies currently face downsizing and turmoil with increasing regularity. In addition, businesses in the post-capitalist society grow through many and varied complicated alliances, often baffling to the traditional manager. In this new world of business, managers must learn to use information in the place of authority as their primary tool. As companies increasingly become temporary institutions, the manager also must begin to explore what Drucker calls competencies: a person's abilities, likes, dislikes, and goals. If executives rise to these challenges, a new organizational foundation will be built. While a combination of rank and power supported the traditional organization, the internal structure of the emerging organization will be mutual understanding and trust.
