The political fokus in the recent decades has been on developing collaborative care. The goal of this is to achive high patient satisfaction, high quality treatment and economic efficiency. The study answers the following questions: What characterizes the current collaboration between public sectors in psychiatric care? How can "management based coaching" be a part of developing collaboration between sectors, to establish and coordinate collaborative care for psychiatric patients? The empirical foundation for the analysis is four interviews with managers and practitioners in the public sector. The analysis and interpretation are based on Ludwig Wittgensteins theory on language games and on Kenneth Gergens theory on organizing dialog. The analysis undercovers an unclear managements concept and a dilemma between standardization and differentiation of the patient care practices. "Ledelsesbaseret coaching" by Thorkil Molly-Søholm et al. offers thorugh organizing dialog, a philosophy on developing a culture of appreciative enquiring, and co-creating dialog. Further the philosophy offers a management concept that combined with the dialog culture creates a culture where the fundamental goals, artifacts, beliefs and visions are reflected opon.
