With new technology, flatter organizations, far-flung virtual teams, and constant change, getting things done at work is tougher and more complex than ever. Managers and executives are trying harder than ever to keep up and stay effective, relying on cross-functional coordination, better planning and resource sharing, simplified processes, and speeded-up work. It's a herculean challenge, and people are struggling. Overcommitment grows and burnout looms.

But even amid the seeming chaos of the matrix organization-where you are constantly being asked to do things by people who aren't your boss-there is always that special person who seems indispensable, who seems to thrive on complexity, and who is able to stay focused and positive and get the right things done: This is the go-to person.

In this game-changing book, Bruce Tulgan reveals the secrets of the go-to person in our new world of work. Based on an intensive study of people at all levels, in all kinds of organizations, Tulgan shows how go-to people not only behave differently, but also think differently, basing their decisions and actions on their own personal influence rather than on any formal designation of authority. At the heart of the go-to person's unique credo are the basics of "the ask" and the response-a powerful reimagining of how to say yes and when to say no.
