This thesis deals with the use of ERP-Systems in the context of production planning and control in medium-sized enterprises. The aim is to give a review of the situation in Austria on the basis of a comprehensive empirical study. The focus is on the description of the current use of IT-Systems in production planning and control, as well as problems and requirements of medium-sized companies in conjunction with ERP-Systems in the production area. At present there is no comparable survey available in Austria, neither in the extent of the sample nor in the level of detail. In the first part of the thesis, structures, functions and tasks of production planning and control are investigated from existing literature in order to fulfil the research assignment.
Furthermore, established experiences were analysed from existing studies and reports and discussed with associate companies from the industry.
Moreover, the dissertation includes a comprehensive survey model which was defined to analyse the facts. In total, three surveys were carried out on over 200 medium-sized enterprises. The main emphasis was placed on a qualitative survey which comprised face-to-face interviews. Based on the factual knowledge of this first research phase two quantitative surveys were accomplished. In the second part of the thesis the most important results of the individual surveys are presented in separated sections. Subsequently, a reflection on all findings is carried out with existing studies and reports. The presentation of the actual situation is completed by the statements of ERP-system-consultants, who voiced their opinion in supplementary qualitative interviews about selected issues. In the final part of the thesis the most relevant results of the empirical study are summarized and subdivided according to the research objectives. Finally future potentials for development are summed up in a forecast.
