Larry Bossidy is one of the world's most acclaimed CEOs, with a track record for delivering results. Ram Charan is a legendary adviser to senior executives and boards of directors, a man with unparalleled insight into why some companies are successful and others are not. Together they've pooled their knowledge and experience into one guide on how to close the gap between results promised and results delivered.

The discipline of execution means understanding how to link together people, strategy, and operations, the three core processes of every business. Leading these processes is the real job of running a business, not formulating a "vision" and leaving the work of carrying it out to others. Bossidy and Charan show the importance of being deeply and passionately engaged in an organization and why robust dialogues about people, strategy, and operations result in a business based on intellectual honesty and realism.

The leader's most important job - selecting and appraising people - is one that should never be delegated. As a CEO, Larry Bossidy personally makes the calls to check references for key hires. Why? With the right people in the right jobs, there's a leadership gene pool that conceives and selects strategies that can be executed. People then work together to create a strategy building block by building block, a strategy in sync with the realities of the marketplace, the economy, and the competition. Once the right people and strategy are in place, they are then linked to an operating process that results in the implementation of specific programs and actions and that assigns accountability. This kind of effective operating process goes way beyond the typical budget exercise that looks into a rearview mirror to set its goals. It puts reality behind the numbers and is where the rubber meets the road.
