Teams are groups of two or more people who work together to achieve common goals and see themselves as part of an organization. Teams form in stages including forming, storming, norming, performing, and adjourning. There are various types of conflicts that can occur within and between teams, such as structural, interpersonal, and intergroup conflicts. Effective teams are informal, participative, have clear tasks and goals, mutual respect, and share leadership while ineffective teams are dominated by a few, have irrelevant discussions, and lack commitment and obligation between members.
