You build a team around top-notch talent. The team members work well together; they're committed to the mission and are highly motivated to perform. Yet the results are disappointing. You're not seeing creativity and flexibility. You're not getting breakthrough ideas. "Good" teams build camaraderie, confidence in their abilities, and a solid process for working together. But these internal dynamics—while positive in themselves—can create a wall between the team and the outside world. And that wall can prevent the team from adapting to change and delivering value to the organization. In this updated, streamlined edition, with a new preface and practical tools, Deborah Ancona and Henrik Bresman describe an externally focused team model—the x-team—that is even more relevant today than when it was first introduced. With their distinctively flexible membership and leadership structure, x-teams continuously reach outward to fuel the innovation process. With new examples and research from organizations such as Microsoft, Takeda, and the Museum of Modern Art, Ancona and Bresman show you how to build x-teams that: In an increasingly complex and ever-changing world, where adaptability and creativity are paramount to an enterprise's success—and even its survival— is your handbook for winning.
