Team building refers to a wide range of activities, usually in a business context, for improving team performance. Team building is pursued via a variety of practices, and can range from simple bonding exercises to complex simulations and multi-day team building retreats designed to develop a team (including group assessment and group-dynamic games), usually falling somewhere in between. It generally sits within the theory and practice of organizational development, but can also be applied to sports teams, school groups, and other contexts. Team building is not to be confused with "team recreation" that consists of activities for teams that are strictly recreational. Teambuilding is an important factor in any environment, its focus is to specialize in bringing out the best in a team to ensure self development, positive communication, leadership skills and the ability to work closely together as a team to problem solve.
