Team structure refers to the way a team is organized to achieve its goals. It defines roles, responsibilities, and relationships among team members. Common structures include hierarchical, where there is a clear chain of command, and flat, which promotes equal participation and collaboration among members. Effective team structures enhance communication and efficiency. They help clarify who is responsible for specific tasks and how decisions are made. A well-defined structure can lead to improved performance and a more cohesive team environment, ultimately contributing to the success of projects and objectives.
