Key Takeaways

Build Trust Through Vulnerability

Lencioni argues that trust and vulnerability form the foundation of a functional team. When team members trust one another enough to be vulnerable, they feel free to admit mistakes, acknowledge weaknesses, and ask for help without fear of judgment. In practice, teams can cultivate this trust by sharing personal histories, encouraging open dialogue, and normalizing imperfection. For instance, Google’s Project Aristotle found that psychological safety—closely aligned with Lencioni’s idea of vulnerability—was the key determinant of high team performance. Organizations can foster this by encouraging leaders to model vulnerability, such as acknowledging when they need support or when a decision didn’t yield the expected results. Though intended for business settings, this advice is applicable in other contexts as well. In educational settings, for example, teachers can build trust by admitting uncertainties and involving students in problem-solving, reinforcing a culture of shared learning.

Encourage Constructive Conflict to Drive Better Decisions

Fear of conflict often results in superficial consensus, preventing issues from being resolved. Lencioni argues that healthy teams engage in passionate debate, but he emphasizes that productive debate must focus on ideas, not personalities. Constructive conflict leads to better decision-making and stronger commitment to shared goals. Practical strategies include setting ground rules for debate, designating roles (such as devil’s advocate), and conducting structured decision reviews. Agile project teams often hold retrospectives to surface disagreements and improve future cycles. In creative industries, brainstorming sessions benefit from open disagreement, which can refine ideas. Leaders must ensure that conflict remains focused on solutions and is not allowed to devolve into personal criticism.

Gain Commitment by Creating Clarity and Buy-In

A lack of open conflict often prevents real commitment to decisions, as team members may feign agreement without true engagement. Lencioni emphasizes that effective decision-making requires that team members be free to voice disagreements. Teams should aim for shared clarity, even if consensus is not unanimous. Techniques like documenting key decisions (along with dissenting opinions), setting deadlines, and assigning ownership can enhance follow-through. This advice is applicable in a wide range of business settings and even beyond the corporate sector. In startup environments, founders often use OKRs (Objectives and Key Results) to crystallize priorities and align efforts. Similarly, teachers or nonprofit managers might involve staff in collaboratively setting term goals to create investment in the outcome. Clarity and commitment are closely tied; without the former, the latter is unlikely.

Hold Each Other Accountable to Shared Standards

Avoidance of accountability is a common dysfunction stemming from fear of interpersonal discomfort. Lencioni advocates peer-to-peer accountability, where team members—not just leaders—call out unproductive behavior. To implement this, teams can use tools like 360-degree feedback, regular peer reviews, and progress dashboards. Similar techniques have already been used both inside and outside the business world. For example, sports teams rely on peer critique to maintain discipline and focus. In workplaces, creating rituals like “accountability check-ins” or “weekly commitments” can reinforce expectations. Managers must also distinguish between supportive feedback and punitive criticism to maintain morale. When team members hold each other to high standards, responsibility becomes distributed, improving performance and engagement.

Prioritize Collective Results Over Individual Status

The final dysfunction Lencioni identifies is inattention to results, where team members prioritize personal goals over collective outcomes. This often stems from ego, departmental silos, or unclear performance metrics. High-functioning teams define success in terms of shared results and establish systems to monitor progress. For example, cross-functional teams might tie bonuses to team-wide KPIs rather than individual performance. In education, teachers might be assessed based on student cohort outcomes rather than isolated test scores. Leaders can reinforce this by publicly celebrating team achievements and aligning incentives with collective success. Cultivating this mindset requires consistent reinforcement and clarity around what “winning” looks like for the team.

Address Dysfunction Holistically, Not in Isolation

Lencioni’s model emphasizes the interdependence of the five dysfunctions—absence of trust, fear of conflict, lack of commitment, avoidance of accountability, and inattention to results. These issues compound one another—with an absence of trust, in particular, giving rise to all the other dysfunctions—meaning that isolated solutions are unlikely to succeed. For instance, a team cannot hold one another accountable if they haven’t first built trust or agreed on clear goals. Practically, this calls for a layered intervention strategy. Off-site leadership activities, team coaching, and diagnostics like Lencioni’s own assessment tool can help map where dysfunctions cluster and what to prioritize. In change management, it’s useful to revisit the model regularly to track progress and recalibrate strategies. Treating team health as an ongoing process, rather than a one-time fix, increases the chances of lasting transformation.


Together, these takeaways create a roadmap for building cohesive, resilient teams. While Lencioni’s model does not address all factors influencing team dynamics, it offers a practical, behavior-focused approach that many organizations find accessible and actionable.
