This post breaks down each dysfunction, explains why they build on each other like a house of cards, and offers practical steps to reverse the damage. Lencioni structures the five dysfunctions as a pyramid. Each lower level enables the one above it. To build a healthy team, you must solve from the bottom up.

The best teams aren’t the ones without conflict. They’re the ones with trust deep enough to fight productively, commit fully, hold each other to high standards, and obsess over collective winning.

Why your team is struggling (and the actionable model to fix it)

Commitment requires two things: (everyone knows the plan) and buy-in (everyone supports it, even if it wasn’t their preferred option).
