Lack of trust. Team members are uncomfortable being vulnerable with one another, unwilling to admit their weaknesses, mistakes or needs for help.
Fear of conflict. Team members are unwilling to engage in passionate, unfiltered debate around important issues.
Inability to commit. Team members fail to achieve buy-in around clear decisions and courses of action.
Unwillingness to hold one another accountable. Team members fail to confront one another around behaviors and deliverables that do not conform to agreed decisions.
Inattention to results. Team members put their individual needs for career development and recognition before the collective goals of the team.
