This document discusses work teams and their increasing popularity in organizations. It contrasts groups with teams, noting that teams generate synergy through coordinated effort to achieve performance greater than individuals. Four types of teams are described: problem-solving teams, self-managed work teams, cross-functional teams, and virtual teams. The key components of effective teams are identified as context, composition, and process. Context includes leadership, resources, and rewards aligned with team goals. Composition considers member abilities, roles, diversity, and size. Effective processes include shared goals, plans, efficacy, and low conflict.
