Gestalt therapy, of all the therapies, might be expected to have developed a literature in this area due to its significant focus on organisational management, both through the Gestalt Institute of Cleveland (GIC) and the Gestalt International Study Centre (GISC) and the body of literature and training they have developed. The theory and practice of Gestalt OSD (Organisation and Systems Dynamics) or GIO (Gestalt in Organisations) is a field or application of Gestalt therapy which has developed for a range of people around the world.
