CONFLICT

The following list of things that destroy teams and organizations from a book The Five Dysfunctions of a Team by Patrick Lencioni.
1. The first dysfunction is an absense of trust among team members. Essentially, this stems from their unwillingness to be vulnerable within the group. Team members who are not genuinely open with one another about their mistakes and weaknesses make it impossible to build a foundation for trust.
2. This failure to build trust is damaging because it sets the tone for the second dysfunction: fear of conflict. Teams that lack trust are incapable of engaging in unfiltered and passionate debate of ideas. Instead they resort to veiled discussions and guarded comments.
3. A lack of healthy conflict is a problem because it ensures the third dysfunction of a team: lack of commitment. Without having aired their opinions in the course of passionate and open debate, team member rarely, if ever, buy in and commit to decisions, though they may feign agreement during meetings.
4. Because of this lack of real commitment and buy-in, team members develop an avoidance of accountability, the fourth dysfunction. Without committing to a clear plan of action, even the most focused and driven people often hesitate to call their peers on actions and behaviors that seem counterproductive to the good of the team.
5. Failure to hold one another accountable creates an environment where the fifth dysfunction can thrive. Inattention to results occurs when team members put their individual needs (such as ego, career development, or recognition) or even the needs of their divisions above the collective goals of the team.
Truly cohesive teams are obvious
1. They trust one another
2. They engage in unfiltered conflict around ideas
3. They commit to decisions and plans of actions.
4. They hold one another accountable for delivering against those plans.
5. They focus on the achievenment of collective results.
