Teamwork involves groups of people working together towards a common goal. There are different types of tasks that can be completed individually or through teamwork. Effective teamwork requires common goals, shared responsibilities, and clearly defined roles. It develops over stages as the team forms, storms, norms and performs. Key skills for teamwork include listening, discussing, questioning, respecting and helping others. Working together efficiently, like migrating geese flying in a V formation, demonstrates the benefits of teamwork.
