This document discusses group dynamics and the five dysfunctions of a team. It outlines Tuckman's stages of group development (forming, storming, norming, performing, adjourning) and ways to promote cohesiveness in groups such as increasing contact time and encouraging external threats. It also describes the five dysfunctions of a team according to Lencioni: lack of trust, fear of conflict, avoidance of accountability, inattention to results, and absence of commitment. Each dysfunction is then explained in how it relates to the others. References are also provided at the end from sources on group dynamics, team building, and productive workplaces.
