Those who work in and with groups experience group dynamics - sometimes pleasant, sometimes frightening. Which forces work in groups and teams? And how can they be controlled constructively? With their knowledge from group dynamic research and practice, Rosa Budziat and Hubert Kuhn support those who work with groups - be they coaches, consultants, group leaders of training groups or members or managers of a team. They explain how it is easier to recognize dynamics in a group and understand better - true to a motto of Kurt Lewin that nothing is more practical than a good theory. And they show that there are numerous ways to work effectively and completely satisfactorily in and with groups and teams. Rosa Budziat and Hubert Kuhn allow a look into their extensive method case, and many case studies illustrate how the group dynamic view of groups and teams can be applied in systemic practice.
