A story about why teams fail: missing trust, fear of conflict, weak commitment, avoided accountability, ignored results.

The key ideas

Trust comes first

In Lencioni’s model, trust means being willing to admit mistakes and weaknesses to teammates. Without it, everything else is guarded.

Healthy conflict is needed

Teams that avoid disagreement make worse decisions and quietly resent each other. Open debate about ideas is a sign of trust, not a lack of it.

Accountability between peers

Strong teams hold each other to standards, not only through the manager.

The criticism

• It is a fable, not a study — the five dysfunctions are a useful lens but not a proven sequence.
• The model can be applied too neatly; real teams have several problems at once and in different orders.

A real-world example

The situation

A student project team keeps agreeing in meetings and then missing deadlines.

The idea applied

One member admits they didn’t understand the brief. Others admit the same. The next meeting has real debate — and a plan everyone actually commits to.

Practise it

In your next team discussion, be the first to say one thing you’re unsure about.
