Explanation:

A team is a group of people who work together toward a common goal. Teams have defined membership (which can be either large or small) and a set of activities to take part in. People on a team collaborate on sets of related tasks that are required to achieve an objective. Each member is responsible for contributing to the team, but the group as a whole is responsible for the team’s success.
Organizations typically have many teams, and an individual is frequently a member of more than one team. Some teams are permanent and are responsible for ongoing activities. For instance, a team of nurses in a maternity ward provides medical services to new mothers. While patients come and go, the tasks involved in providing care remain stable. In other cases a team is formed for a temporary purpose: these are called project teams and have a defined beginning and end point linked to achieving a particular one-time goal.
Organizations form teams to accomplish tasks that are too large or complex for an individual to complete. Teams are also effective for work that requires different types of skills and expertise.
