Group processes in organizations.

The article refers to group processes as they influence organizational functioning. The main features of groups (e.g., norms, cohesion, roles), and factors contributing to their performance are characterized. We detail well-established concepts like groupthink and social identity theory. Further, we refer to important current topics in organizational practice and research related to group functioning, like team mental models, diversity in groups, and counterproductive work behavior. Finally, hints at the practical relevance in terms of the implementation of these concepts in organizational contexts are provided (e.g., organizational change, leadership in multinational corporations, and shared leadership)
