The Five Dysfunctions of a Team (Patrick Lencioni)

What are the five dysfunctions of a team and how do you fix them?

Lencioni’s pyramid — the mechanism behind each dysfunction and the practice that fixes it

Short answer

Patrick Lencioni’s model describes five compounding failures that undermine teams: absence of trust, fear of conflict, lack of commitment, avoidance of accountability, and inattention to results — each built on the one below. It is a practitioner framework presented as a business fable, not an empirically tested model, but its five dimensions align well with decades of team effectiveness research, making it a useful diagnostic even without controlled-trial support.

Lencioni’s argument is that team failure is rarely about strategy or talent — it’s about compounding interpersonal failures that each make the next one possible. Trust enables productive conflict; conflict enables real commitment; commitment enables peer accountability; accountability enables collective focus on results. Break any level, and the ones above collapse with it. Below are the five dysfunctions with the practices that address each, and an honest read on where the evidence is real.

Why it works

Lencioni distinguishes vulnerability-based trust — the comfort to show your real limitations — from predictability-based trust (knowing someone will do what they say). Teams can be predictable and still be guarded. Vulnerability-based trust accelerates because it shortcuts the slow process of inferring character from behavior: when someone says "I was wrong" or "I don’t know," others update their model of them rapidly and positively. That update makes self-disclosure reciprocal, which is the foundation of psychological safety.

How to do it
  1. 1Start with structured personal sharing in low-stakes settings — brief, genuine self-disclosure from leaders before anyone else.
  2. 2Leaders must go first and go real: performative vulnerability ("I’m not perfect either!") is detectable and counterproductive.
  3. 3Use personal history exercises: ask each person to share something about their background that the others wouldn’t know and that affected how they work.
  4. 4Make admitting mistakes and ignorance the norm in meetings — model it, reward it, never weaponize it.
Evidence
Observational

Vulnerability-based trust aligns with Edmondson’s psychological safety research, which shows that teams where interpersonal risk-taking is safe show higher learning and performance. Lencioni’s specific framing is practitioner-derived; the underlying construct is well studied.

Honest caveat: Psychological safety research is observational (correlational); Lencioni’s "vulnerability-based trust" is his prescriptive label for a related but distinct construct. The causal direction is supported by field research but not established by controlled experiments.

Common mistake: Asking team members to be vulnerable before the leader has modeled it — people take their cue from the top; asking for openness without demonstrating it first produces a performance of vulnerability, not the real thing.
