Non-profit-organisations need special management. In the non-profit-sector high quality competence must be given as services in this particular area are provided to the people in care. Service, innovation and economic efficiency are being analysed more and more in non-profit-organisations and sometimes even compared with the economic sector. Competent executives and skilled employees are necessary to fully meet these requirements. Appropriate motivation and promotion of the employees lies therefore within the responsibility of the executives. Supervision is among others a tool for personnel development measures, with which the quality of the organisation can be preserved and developed. In this master thesis the effects of supervision on top levels in non-profit-organisations, if employees are provided with the possibility of taking supervision, will be researched. Chances as well as challenges for executives in the non-profit-sector, which occur when supervision is being used, will be defined. Additionally framework conditions for a successful use of supervision, which should be given by the organisation and executives, will be presented. The authoresses' central research questions address executives in the management level of non-profit-organisations in Vorarlberg/Austria. On the basis of structured interviews relevant data concerning supervision, personnel development, quality management and learning organisations will be empirically collected and evaluated.The results show that supervision as a human resources development instrument on management level is increasingly focusing and strengthen the functional efficiency referring to quality assurance. Despite everything, supervision must be seen as one amongst many possible measures, which can lead to a long-term success in non-profit-organisations.
