Nobody sets out to lead an ineffective team. In fact, leaders agonize over fostering teams that work well together and deliver smart solutions time and time again—the kind of teams that, in Leigh Thompson’s words, “go through the various storms, the successes, the failures, and keep coming out alive.” The only problem? Many of the strategies leaders have adopted to improve teamwork, while well-intentioned, are not all that effective. Thompson, a professor of management and organizations at Kellogg and an expert on teamwork, clears up five popular misconceptions. In the process, she offers a roadmap for building and maintaining teams that are creative, efficient, and high-impact.
