Definitions of Team
A team is more than just a group of people working together—it’s a dynamic unit where collaboration, trust, and shared purpose drive superior performance.
From Drucker’s classic definition of “complementary skills and mutual accountability” to Google’s research on psychological safety, the essence of effective teams has been decoded by management’s greatest thinkers.
This article compiles 25 foundational definitions from Katzenbach, Lencioni, Edmondson, and others, revealing how teams:
- Transform individual effort into collective success
- Evolve through conflict and cohesion
- Thrive on trust and clear goals
Whether in agile startups or Fortune 500s, these insights remain vital for building high-performing teams.
Let’s look at the 25 top definitions of teams in the business world.
