The Five Dysfunctions of a Team is a book that, through a fable format, explains what works and what doesn’t work with teams.
TPM Strategic Takeaway: Mainstream corporate, lacks depth and deeper power-insights
The Five Dysfunctions of a Team is a mainstream management model explaining why teams fail across five areas: trust, conflict, commitment, accountability, and results. It is useful as a simple corporate framework, but it is not a deep or scientific model of group behavior. From a TPM perspective, it should be read as a surface-level description of team coordination problems, which can be reinterpreted through underlying power, incentives, and status dynamics.

Notes
About the Author:
Patrick Lencioni is an American writer of business books, particularly focusing on leadership and team management.
Foreword
“The Five Dysfunctions of a Team” uses a made up story to explain the key tenets of what makes a functional or dysfunctional team.
I will skip the story for the most part and focus on the key takeaways.
Cohesiveness
It’s not easy to exactly define what makes team great, but there is a lot of consensus around one trait: cohesiveness.
Cohesiveness is the adjective that identifies “teamwork”.
The importance of cohesiveness can be routinely experienced in team sports, where a cohesive team of good or even average players routinely beat the dysfunctional team of stars.
Why Talented Teams Perform Poorly Without Teamwork
Patrick Lencioni says that the (potentially) star performers in poor teams waste time and energy in politics and game playing.
The politics and games take focus away from work and performance, resulting in lower morale, lower engagement and lack of focus.
#1. Trust: The Foundations of Great Teams
When there is trust the team is free to communicate openly about any issue, which leads to all issues being brought to the table.
And for all issues being brought to the table, everyone feels free to say what they think, and the best solution is more likely to emerge -without anyone getting hurt-.
To foster trust, the author says people must embrace vulnerability.
And the first person to show vulnerability should be the leader. In the parable of DecisionTech, the new CEO Kathryn Peterson started by sharing her weaknesses, her past mistakes and even admitting she had been fired in the past.
My Note:Â Oversimplification of open communication
There are deeper psychological and power-related issues that contribute to a team opening up or not, including diverging interests, level of competitiveness, advantages/disadvantages of cooperation, and dark triad traits in the team
#2. Constructive Conflict
Constructive conflict is what allows teams to openly debate ideas. And openly debate idea is the best way to increase the likelihood of reaching the best possible decision.
To be constructive a conflict must be focused on the topic and decision, and not on personal agendas.
#3. Commitment
Great teams know that a decision is better than no decision at all.
And they put their personal egos and agendas aside to stand behind any decision: even the ones they didn’t initially want.
Lencioni says that it’s critical that everyone gets a chance to be heard.
Once people feel that their opinion has been heard and considered that’s often enough to make them feel as part of the decision making, even if the final decision is not what they advocated for.
#4. Peer to Peer Accountability
For me this was the best and most insightful part of “The Five Dysfunctions of a Team”.
The author says that when good rapport develops in a team people also become reluctant to hold each other responsible for results and top performance.
Ironically, that’s exactly what ruins those relationships as people hold back from what they really think and resentment can fester.
Also when there is no peer accountability, everyone feels less accountable for the final result. And the full omen of discipline and keeping a high standard falls to the team leader.
But when there is trust in a team people know that any possible criticism is not a personal attack but it’s for the common good.
And they come to respect colleagues who help them tweak their performance as they know everyone is adhering to the same high standards.
#5. Focus on Collective Results
Great teams don’t focus on personal achievements, but on collective, team achievements.
The author uses the example of Kathryn’s husband, a basketball coach who had to let go of the most talented player in the team because he didn’t care whether the team won or lost, but only for how much he scored.
Lencioni says that the best goals are clearly defined and easy to measure.
My Note: Broad stroke take for average teams rather than top performer
I don’t see necessarily a dichotomy between “own selfish interests” and team’s interests.
Also, many star performers are often pushed to achieve by their high drive and hunger for victory. I don’t think that superstars should be dropped by the team, but you should find solutions to make their talent work for the collective good.
For example, at DecisionTech Katryn’s goal was to have 18 customers by the end of the year.
That was a common goal for everyone.
The result was that there were fewer fiefs in the company. The engineering department was willing to help and support the sales team instead of protecting its resource to achieve its own goals.
Great Team Spend Time Together
Lencioni makes the point that great, top-performing teams, spend a lot of time together.

Real Life Applications
Hold Colleagues Accountable Strategically
Don’t be afraid of holding colleagues accountable. If you don’t, it will breed resentment. However, if you do poorly you can make enemies. So be careful. Do it tactfully, it will develop trust and respect.
Lead by Example
If you’re the team leader, but also if you’re a team member, never forget this simple rule: be the change you want to see in others.
Be the change you wish to see
CRITICISM
Black & White View of Personal Ambition vs Collective Results
I feel that the personal drive for achievement does not stand in direct contrast to good teamwork. We all have our own egoistical drive and we should leverage the team for results, and not try to squash them.
Demonizies Selfish Drives: They’re Natural, Not Always Harmful
Lencioni tends to label personal drives as “harmful”, which is a common but imperfect way of looking at what is, after all, a natural drive for each one of us. Correct handling of selfishness is about managing and channeling, not repressing it or demonizing it.
Review
“The Five Dysfunctions of a Team” is a corporate management classic touching on several foundational elements of effective team, but also missing out on other crucial aspects of psychology and power dynamics.
By largely skipping the ‘darker’ aspects of socialization, such as diverging interests, manipulation, or negative elements that must be handled, it’s also a classic ‘naive self-help‘.
