The Five Dysfunctions of a Team: A Leadership Fable, 20th Anniversary Edition (J-B Lencioni Series Book 43)

The Five Dysfunctions of a Team by Patrick Lencioni is a bestselling leadership classic that explores why even strong teams fail—and how to fix it.

Told through the story of Kathryn Petersen, the new CEO of DecisionTech, the book follows her struggle to unite a deeply dysfunctional executive team threatening the company’s future.

Blending a compelling business fable with practical insights, Lencioni identifies five core issues—absence of trust, fear of conflict, lack of commitment, avoidance of accountability, and inattention to results—and provides a clear framework to build cohesive, high-performing teams.

Now celebrating its 20th anniversary, this timeless handbook remains an essential guide for leaders seeking unity and success.
