Lencioni’s model explains that team effectiveness is often undermined by a series of interconnected dysfunctions. These dysfunctions form a hierarchy, meaning that each one builds on the one before it (Lencioni, 2012). Addressing them requires understanding how they relate to one another rather than treating them as separate issues.
The first dysfunction is the absence of trust. This occurs when individuals are unwilling to be vulnerable with one another (Lencioni, 2005). Without trust, people may avoid admitting mistakes, asking for help, or sharing concerns. This limits openness and creates a guarded environment where collaboration is restricted. Trust forms the foundation for all other aspects of teamwork, making it critical to overall effectiveness.
The second dysfunction is the fear of conflict. When trust is low, teams struggle to engage in open and honest debate (Lencioni, 2005). Instead of discussing ideas fully, individuals may avoid disagreement or suppress their views. This can lead to decisions that are not fully explored or understood. Productive conflict is not about personal disagreement but about exploring ideas to reach better outcomes.
The third dysfunction is a lack of commitment. When individuals do not feel that their views have been heard, they are less likely to fully support decisions (Lencioni, 2005). This can result in uncertainty, hesitation or lack of clarity about direction. Commitment is strengthened when individuals are involved in discussions and understand the reasoning behind decisions.
The fourth dysfunction is the avoidance of accountability. Without commitment, individuals may be reluctant to challenge others on behaviours or actions that affect performance (Lencioni, 2005). This can lead to lowered standards and inconsistency within the team. Accountability is not about blame but about maintaining shared expectations and ensuring that commitments are upheld.
The fifth dysfunction is inattention to results. When accountability is weak, individuals may prioritise personal goals over team outcomes (Lencioni, 2005). This shifts focus away from collective success and reduces overall effectiveness. A strong focus on results ensures that effort is aligned with shared objectives.
These dysfunctions represent patterns of behaviour that limit team effectiveness (Clutterbuck, 2019). They are not fixed traits but can be addressed through deliberate action (Spencer & Smedick, 2025).

A key strength of the model is its simplicity. It provides a clear framework for identifying challenges within a team and understanding how they are connected. By addressing the root dysfunctions, particularly trust, it becomes possible to influence all other areas of team performance (Burris‐Melville & Burris, 2023).
The model also highlights the importance of behaviour over structure. While processes and systems are important, how individuals interact plays a critical role in determining success. This reinforces the idea that improving team effectiveness requires attention to relationships, communication, and shared responsibility (Schreiber, 2024).
In practice, applying the model involves observing team behaviour and identifying where dysfunctions are present. This creates a starting point for improvement. By focusing on building trust, encouraging open discussion, strengthening commitment, promoting accountability and maintaining focus on results, teams can improve how they work together.
Overall, Lencioni’s Five Dysfunctions of a Team provides a practical and accessible way to understand and improve team effectiveness. It emphasises that successful teams are built on strong relationships, open communication and a shared commitment to results.
Action Point
Reflect on a current team and identify which of the five dysfunctions is most visible. Focus on one area, such as trust or accountability, and take a specific action to address it. This could include encouraging open discussion, clarifying expectations or creating opportunities for feedback. Review the impact over time and adjust as needed. Small, consistent changes can strengthen team effectiveness.
