Maintenance is an important factor for the effectiveness of production processes. As the degree of automation and interoperation of production equipment is increasing, the significance of equipment availability and thus of maintenance is increasing. At the moment, maintenance and service engineers spend a lot of time in retrieving and preparing information. In many cases the data of business information systems is not or only partly available to maintenance engineers. In the future, resource-cockpits on mobile devices will provide maintenance and service engineers with all necessary information in situ. This will be realised interactively, with little effort and in the right context.
