Service technicians in the Technical Customer Service (TCS) domain have to deal with different duties at the point of service in a short time. To tackle these challenges, information systems have to be developed to support their everyday work. In the joint project EMOTEC we aim to improve the efficiency of service technicians by intelligent mobile assistant systems. Key component of our system is an integration platform for effective data storage and -integration that facilitates repair processes. The platform under development provides flexible support and has the potential to both increase the productivity and the empowerment of the service technician.
