Team structures refer to the way a group is organized to achieve specific goals. Common types include functional teams, where members have similar skills and roles, and cross-functional teams, which bring together individuals from different departments to collaborate on projects. Each structure has its advantages, such as improved communication or diverse perspectives. Another important aspect of team structures is the hierarchy within the team. In a hierarchical structure, there are clear levels of authority, while a flat structure promotes equal participation among team members. The choice of structure can impact decision-making, efficiency, and overall team dynamics.
