This thesis focuses on the empirical analysis of the organisational solutions small and medium sized enterprises (SMEs) undertake in order to integrate product accompanying services. Therefore, with the help of a written survey in the metal and electrical industry the service offers of this industrial branch and the organisational implementation of these services will be analysed. Detailed case studies show that the majority of these services is generated in addition to the work performed for the machine production itself. Furthermore these services have to be generated in a holistic way and to be organised by the workers themselves. Resulting from the interaction between this work organisation typical for SMEs and the service sector specific features (difficult to be planned, interaction with the customer) these working conditions blur the boundary between work life and private life. Therefore, these working conditions (being known as "Entgrenzungs- und Subjektivierungsphänomene" in the German debate) do not only play an ever increasing important role in the New Economy and the large-scale industry, but also for the service actors in the engine building industry.
