Final answer:
A team is a unit of individuals with complementary skills dedicated to common goals and mutual accountability, often formed in businesses to address complex tasks.
Step-by-step explanation:
A team is described as a small number of people with complementary skills who are committed to a common purpose, set of performance goals, and an approach for which they hold themselves mutually accountable. This definition reflects the collaborative nature of a team that is often brought together in the workplace to tackle specific tasks or goals, leveraging their diverse skills, experiences, and expertise. It contrasts with other types of groups such as committees, which are officially delegated to perform a function, or reference groups, whose values and norms may influence an individual's behavior. When it comes to organizing for efficiency and innovation, many organizations favor the team-based approach for its potential to address complex problems and adapt quickly to changes in technology, economics, and demographics.
