The Five Behaviours of a Cohesive Team®
What it actually takes for a team to work.
Most teams are not failing because people lack capability. They are failing because the conditions for genuine cohesion have never been built. The Five Behaviours of a Cohesive Team® is a programme developed by Wiley in partnership with Patrick Lencioni, based on his bestselling book The Five Dysfunctions of a Team. It gives teams a shared model for understanding what gets in the way of real cohesion, and a structured process for doing something about it.
The five behaviours build as a pyramid, each layer depending on the one beneath it. Trust is the foundation. Without it, conflict stays polite and unproductive. Without honest conflict, commitment is superficial. Without commitment, accountability is personal rather than collective. And without accountability, results suffer, not because people are not capable, but because the team is not actually functioning as one.
Most teams recognise themselves somewhere in that sequence. The power of the model is not in the diagnosis. It is in what happens when a team works through it together, with proper facilitation and enough psychological safety to be honest.
What makes Five Behaviours different
Most team development focuses on what a team does. Five Behaviours focuses on how a team is. That distinction matters because you can run any number of away days, alignment sessions, and communication workshops without ever touching the real dynamics that are limiting performance. Five Behaviours goes there directly.
It is also cumulative in a way that one-off interventions rarely are. Each behaviour builds on the last, which means the programme has a structural logic that teams can feel as they work through it. Progress is visible, which sustains engagement in a way that more abstract development work often fails to.
Kate’s experience of Five Behaviours, from the inside
Most practitioners have delivered Five Behaviours. Kate has lived it, twice, as a senior leader on two teams that commissioned the programme, not as the facilitator in the room but as a participant navigating real dysfunction alongside colleagues.
The first was a functional marketing team where the tensions were lateral and longstanding, the kind that accumulate quietly until they calcify into fixed patterns nobody names. The second was a corporate marketing team with a Chief Marketing Officer in the room, which changes everything: the power dynamics, what people are willing to say, and what the leader hears versus what is actually meant.
Both experiences were uncomfortable in the way that genuine development work always is. Both shifted something real. And both inform how Kate facilitates the programme now, with an understanding of what it actually feels like to sit in those sessions as a participant rather than an observer. That experience is not incidental. It is the difference between a practitioner who can explain the model and one who knows what it is like to be asked to trust a team you are not sure you trust yet.
How we use Five Behaviours at We Are Firestarter
We are certified Five Behaviours practitioners and use the programme as a core strand of our team development work.
For teams commissioning a sustained development programme, Five Behaviours provides the diagnostic backbone and the shared language that makes everything else land. Each participant completes the assessment before the sessions begin, and the facilitated sessions work through each behaviour in sequence, grounded in the team's own data rather than generic examples.
For teams who want a more focused intervention, we can also work with individual elements of the model, whether that is trust-building following a difficult period, improving the quality of conflict in leadership team meetings, or strengthening accountability structures that have gradually eroded.
Every Five Behaviours engagement starts with a conversation about what the team is actually navigating. The programme is highly effective and also demanding, and the right conditions matter. We will always be honest about whether this is the right moment for your team.
Five Behaviours and Everything DiSC®
The two models work powerfully together. Everything DiSC® helps teams understand the why behind their differences in style, communication, and decision-making. Five Behaviours gives them the structure to address what those differences are doing to their cohesion and performance. We often use both within the same team development programme, sequencing them so that the DiSC work deepens the self-awareness that Five Behaviours then puts to work.

The original and still the most accessible treatment of why teams fail. Written as a leadership fable, which makes it unusually readable for a business book. The model behind the Five Behaviours programme is built directly from it.

Her research across six decades of team studies shows that psychological safety is the single strongest predictor of team performance.

Is Five Behaviours right for your team?
Five Behaviours works best with teams that have real interdependence, a genuine need to work together rather than simply co-exist, and enough psychological safety to begin being honest. It is not a good fit for teams where trust has broken down so completely that mediation or individual coaching is the more appropriate starting point. We will always tell you which applies.
