Patrick Lencioni vs Amy Edmondson: Five Dysfunctions or Psychological Safety?
Comparing Patrick Lencioni's model of team dysfunction with Amy Edmondson's research on psychological safety: where they overlap, how they differ, and when each helps a struggling team.
Anyone fixing a struggling team meets two sources soon: Patrick Lencioni's The Five Dysfunctions of a Team, a business fable that became a standard offsite tool, and Amy Edmondson's research on psychological safety, which Google's own team study made famous. People compare them because both name trust and candor as foundations.
What is the core difference?
Lencioni gives a diagnosis in the form of a story. A team lacks trust, so it avoids conflict, so it fails to commit, so it avoids accountability, so it ignores results. The model is easy to remember and discuss.
Edmondson gives a finding. Teams differ in whether members believe they can speak up without being punished, and this difference predicts learning and performance. The research includes measures and shows how leaders influence it.
One gives teams a vocabulary. The other gives leaders evidence and a set of behaviors.
What does Lencioni say?
Patrick Lencioni is a consultant and author, and founder of The Table Group. The Five Dysfunctions of a Team (2002) presents its model through a fictional company. The Advantage (2012) argues that organizational health is the biggest advantage a company can have. The Ideal Team Player (2016) says the best team members are humble, hungry, and smart.
His material is widely used in leadership training. It is based on his consulting experience, and his organization sells workshops, assessments, and materials built on the models.
What does Edmondson say?
Amy Edmondson is a professor at Harvard Business School. Her research on psychological safety began in the 1990s with studies of how teams handle errors. Teaming (2012) and The Fearless Organization (2019) lay out the ideas for practitioners, and Right Kind of Wrong (2023) examines different types of failure.
She describes three leader tasks: set the stage, invite participation, and respond productively. Google's Project Aristotle later found psychological safety to be an important factor in team effectiveness at the company, which brought wide attention to the concept.
How do they compare?
| Dimension | Lencioni | Edmondson |
|---|---|---|
| Source | Consulting experience and a business fable | Academic research and field studies |
| Core model | Pyramid of five dysfunctions | Psychological safety and three leader tasks |
| Starting point | Absence of trust | The belief that interpersonal risk is safe |
| Typical use | Team offsites and diagnostic workshops | Leadership behavior and team climate surveys |
| Ease of use | Simple and memorable | More demanding; depends on behavior over time |
| Main risk | Treating the pyramid as proof, or as a one-day fix | Treating safety as comfort, or measuring without acting |
| Best known for | The Five Dysfunctions of a Team (2002) | The Fearless Organization (2019), Teaming (2012) |
When does each one fit?
Lencioni's model fits when a team needs a shared way to talk about what is wrong. The pyramid helps people name the problem and agree on which layer to work on first, and the exercises give a structure for the conversation.
Edmondson's work fits when you want to understand why people stay silent and what a leader can change. Her guidance on how to respond to bad news and invite input addresses behavior that determines whether any model works.
A team without any common language may start with the pyramid. A team that has the language and still does not speak up needs the leader's behavior in Edmondson's account.
What does this look like in practice?
A leadership team is polite in meetings and nothing changes. A Lencioni reading sees fear of conflict resting on weak trust: people do not disagree openly because they do not feel safe being vulnerable. The offsite includes exercises on personal histories and on practicing productive conflict.
An Edmondson reading asks how the leader responds when someone raises a problem. If the first dissent receives a defensive answer, the lesson spreads quickly. The remedy is a change in the leader's response, repeated over time. The two readings point in the same direction, and the second tells the leader what to do on Monday.
"My team is [description] and the main symptom is [symptom]. First, using Lencioni's five dysfunctions, tell me which layer is most likely the root problem and what evidence supports it. Then, using Edmondson's three leader tasks, tell me what I might be doing, or not doing, that makes it easier or harder for people to speak up, and suggest one change to test over the next month."
Why it works: the pyramid names the layer, and the leader tasks name the behavior.
Can you use both together?
Yes, and they fit well. Use the pyramid to make a team conversation concrete, and use Edmondson's research to inform what the leader does around it. A workshop on trust without a change in how bad news is received will fade.
The shared risk is a one-time event. Both authors treat the work as ongoing.
"We held a team session on [topic]. Draft a ninety-day plan that turns it into behavior: three specific leader actions in meetings, one question to ask in each one-on-one, a way to notice whether people are raising problems earlier, and a check-in at thirty, sixty, and ninety days."
Why it works: a follow-through plan turns insight into repeated behavior, which both authors say is what changes teams.

Frequently asked questions
Do Lencioni and Edmondson describe the same problem?
They overlap strongly. Lencioni's first dysfunction is absence of trust, which he defines as a team's willingness to be vulnerable with one another. Edmondson's psychological safety is the belief that it is safe to take interpersonal risks. They arrive from different directions, he as a consultant writing a fable, she as a researcher. Many readers treat the two as describing neighboring ideas.
What are the five dysfunctions?
In The Five Dysfunctions of a Team (2002), Lencioni lists absence of trust, fear of conflict, lack of commitment, avoidance of accountability, and inattention to results. He arranges them as a pyramid in which each depends on the one below. The model is presented as a way to diagnose where a team is stuck, based on his consulting experience. Lencioni argues that conflict, in the sense of passionate debate about ideas, is healthy once trust exists.
What is the ideal team player?
In The Ideal Team Player (2016), Lencioni argues that the best team members are humble, hungry, and smart, meaning good with people. He describes how missing one of the three produces a recognizable type, such as a pawn or a bulldozer. It is a hiring and coaching model from his consulting practice, not a result of controlled research. Each type has a strength that is missing one of the three virtues, which makes the model useful for coaching conversations.
Which has better evidence?
Edmondson's psychological safety rests on decades of published academic research in journals, plus field studies, though findings differ by setting. Lencioni's model rests on consulting experience and a narrative, and has been used widely but is not a research finding. That does not make it unhelpful, but the two have different standards of proof. Both are widely used in practice, but only one comes with a body of peer-reviewed evidence behind it.
Which is easier to use in a workshop?
Lencioni's pyramid is simple to explain, and his group exercises are widely used in team offsites. Edmondson's work has survey tools and recommendations, but is more often applied through leadership behavior over time. Teams that want a structured conversation often start with the pyramid, and those seeking diagnosis by data often use safety surveys. A reasonable approach is to use a workshop to open the conversation and then use behavior and measurement to sustain it.
Can AI facilitate a team assessment?
It can draft survey questions, summarize results, and suggest discussion prompts. It cannot read the room or judge whether people are being candid. Use it to prepare and to organize findings, and keep sensitive conversations with a skilled human facilitator. Keep in mind that candid conversations about trust need a skilled human who can notice discomfort and slow things down.
