The Master Thesis covers an analysis of the effectivity and efficiency of institutions of the Austrian Health Administration System. The development potentials are clearly represented with a special focus on the current management structures.Seven managerial employees have been interviewed as experts to provide, beside a substantiated theoretical basis, a solid foundation and insight for the analysis. As subjects of study about the given management conditions, the following institutions have been covered: The Province of Styria (Land Steiermark), the Association of the Austrian Social Insurance Agencies (Hauptverband der österreichischen Sozialversicherungsträger), the Austrian Medical Association (Österreichische Bundesärztekammer), the Styrian Statutory Health Insurance Agency (Steiermärkische Gebietskrankenkasse), the Federal Ministry of Health (Bundesministerium für Gesundheit), the National Health Agency (Bundesgesundheitsagentur), the Styrian Provincial Health Fund (Landesgesundheitsfonds Steiermark) and the Styrian Hospital Management Organization (Steiermärkische Krankenanstaltengesellschaft).The results of the study can be summarized as that there are several different development potentials in terms of the efficiency and the effectivity of management activities. There is especially a lack of an overall consistent strategy development process, with which it would be possible to implement individualized operative tasks for the involved single institutions. Also, there is a distinctive difference in the corporate cultures and a conflict of interests between the institutions in the health system, which massively hinders an effective and efficient cooperation of the institutions. Beside the lack of an equal allocation of power in the centralized steering committee, also the absence of an independent superior monitoring institution, which supervises and evaluates the achievement of the agreed tasks by the individual institutions, has to be criticized.
