Based on Patrick Lencioni's work,'The Five Dysfunctions of a Cohesive Team':
Trust: When team members are genuinely transparent and honest with one another, about their performance and their behaviours, they are able to build vulnerability-based trust – the capacity to say 'I'm sorry,' 'I need help,' 'I got it wrong,' etc.
Conflict: When there is trust, team members are able to engage in unfiltered constructive debate of ideas.
Commitment: When team members are able to offer opinions and debate ideas, they are able to obtain clarity and buy-in and are more likely to commit to decisions.
Accountability: When everyone is committed to a clear plan of action and they trust one another, they will be more willing to hold each other accountable and achieve peer accountability.
Collective Results: The ultimate goal. A group of individuals becomes a team when there is shared responsibility for, and shared commitment to the success of the team. Effective teams share the credit when goals are achieved and the responsibility when they are not.
