This paper describes the course and the results of a research and development project that is a textbook case for business informatics projects. Starting with the idea for new communications technology and the ensuing goals, we describe the design along with the logical and technical architecture of the core result -- a software framework to serve as the technological basis for the development of software-intensive location-based systems. To show which solutions were selected to master special problems related to location-based services, we present selected design details. In addition, we describe important aspects of the management of large R&D projects and the practical application of research results, both of which are essential from the perspective of business informatics.
