Starting from the historical evolution of the value-added chain theory, the question will be answered, with what approaches the operational supply chain can be designed. In addition, the role of networks and information and communication technology and the importance of creating value for the public sector will be formulated. From the insights gained from the first part, the goals of the Supply Chain Management (SCM) will be defined. Afterwards, the question will be answered, how these goals can be achieved. For this purpose, optimization potentials will be derived from the target formulations. In concrete terms, the pros and cons of outsourcing and integration of business processes will be discussed. Furthermore a comparison of these two strategy approaches will be defined. During the optimization of the value-added chain, the concept of "Deconstruction of the value-added chain" will be analyzed. The theoretical work-up will be followed by an empirical part. In this part managers and experts of the Styrian industry will be interviewed about their opinion concerning the trends in the SCM in their branches and the industry as a whole. The aim of this survey is to elicit industry specific trends and to compare these with the previously developed theoretical approaches. In Special the empirical part tries to find out whether the trend goes toward outsourcing or integration. Several companies in four different sectoros will be interviewed in order to gain meaningful results. In the last section of the Master thesis, knowledge obtained from the first two parts will be discussed and compared. Furthermore the results will be analyzed in a critical discourse in order to derive conclusions and recommendations.
