A team comprises a group of people or animals linked in a common purpose. Teams are especially appropriate for conducting tasks that are high in complexity and have many interdependent subtasks.
A group in itself does not necessarily constitute a team. Teams normally have members with complementary skills and generate synergy through a coordinated effort which allows each member to maximize his/her strengths and minimize his/her weaknesses. Team members need to learn how to help one another, help other team members realize their true potential, and create an environment that allows everyone to go beyond their limitations.[1] A team becomes more than just a collection of people when a strong sense of mutual commitment creates synergy, thus generating performance greater than the sum of the performance of its individual members.
Thus teams of game players can form (and re-form) to practise their craft. Transport logistics executives can select teams of horses, dogs or oxen for the purpose of conveying goods.
Theorists in business in the late 20th century popularised the concept of constructing teams. Differing opinions exist on the efficacy of this new management fad. Some see "team" as a four-letter word: overused and under-useful. Others see it as a panacea that finally realizes the human relations movement's desire to integrate what that movement perceives as best for workers and as best for managers. Still others believe in the effectiveness of teams, but also see them as dangerous because of the potential for exploiting workers — in that team effectiveness can rely on peer pressure and peer surveillance.
Compare the more structured/skilled concept of a crew, and the advantages of formal and informal partnerships.

Team size and composition affect the team processes and outcomes. The optimal size (and composition) of teams is debated and will vary depending on the task at hand. At least one study of problem-solving in groups showed an optimal size of groups at four members. Other works estimate the optimal size between 5-12 members.[citation needed] Belbin did extensive research on teams prior to 1990 in the UK that clearly demonstrated that the optimum team size is 8 roles plus a specialist as needed.[2] Fewer than 5 members results in decreased perspectives and diminished creativity. Membership in excess of 12 results in increased conflict and greater potential of sub-groups forming.
David Cooperrider suggests that the larger the group, the better. This is because a larger group is able to address concerns of the whole system. So while a large team may be ineffective at performing a given task, Cooperider says that the relevance of that task should be considered, because determining whether the team is effective first requires identifying what needs to be accomplished.
Regarding composition, all teams will have an element of homogeneity and heterogeneity. The more homogeneous the group, the more cohesive it will be. The more heterogeneous the group, the greater the differences in perspective and increased potential for creativity, but also the greater potential for conflict.
Team members normally have different roles, like team leader and agents. Large teams can divide into sub-teams according to need.
Many teams go through a life-cycle of stages, identified by Bruce Tuckman as: forming, storming, norming, performing and adjourning.
Of particular importance is the concept of different types of teams. A distinction is usually drawn between "independent" and "interdependent" teams. To continue the sports team example, a rugby team is clearly an interdependent team:
On the other hand, a chess or bowling team is a classic example of an independent team:
Coaching an "interdependent" team like a football team necessarily requires a different approach from coaching an "independent" team because the costs and benefits to individual team members — and therefore the intrinsic incentives for positive team behaviors — are very different. An interdependent team benefits from getting to know the other team members socially, from developing trust in each other, and from conquering artificial challenges (such as offered in outdoors ropes courses).
Although the concept of a team is relatively simple, many different types of teams have been identified by social scientists. In general, teams either act as information processors, or take on a more active role in the task and actually per form activities. The following are some common categories and subtypes of teams.
Teams, such as in medical fields, may be interdisciplinary or multidisciplinary.[6] Multidisciplinary teams involve several professionals who independently treat various issues a patient may have, focusing on the issues in which they specialise. The problems that are being treated may or may not relate to other issues being addressed by individual team members. Interdisciplinary team approach involves all members of the team working together towards the same goal. In an interdisciplinary team approach, there can often be role blending by members of the core team, who may take on tasks usually filled by other team members.[6]
Some people also use the word "team" when they mean "employees." A "sales team" is a common example of this loose or perhaps euphemistic usage, though inter dependencies exist in organisations, and a sales team can be let down by poor performance on other parts of the organisation upon which sales depend, like delivery, after-sales service, etc. However "sales staff" is a more precise description of the typical arrangement.
Groups develop into teams in four stages. The four stages are: dependency and inclusion, counter dependency and fighting, trust and structure, and work. In the first stage, group development is characterized by members' dependency on the designated leader (Identical to 'Forming' in Tuckman's model). In the second stage, the group seeks to free itself from its dependence on the leader and groups have conflicts about goals and procedures (Identical to 'Storming' in Tuckman's model). In the third stage, the group manages to work through the conflicts (Identical to 'Norming' in Tuckman's model). And in the last stage, groups focus on team productivity (Identical to 'Performing' in Tuckman's model).[7][clarification needed]
