Case studies

Abstract

To obtain input from practice and to validate the concepts and techniques explained in the previous chapters, several partner-specific case studies have been executed. These have also served as an important means for knowledge transfer from research to practice. This chapter will elaborate on three of these case studies. The first two cases, of ABP and ABN AMRO, focus on supporting an architecture description of the current situation. In both cases, integration of heterogeneous descriptions using different ‘languages’ is a central issue. Furthermore, it exemplifies the use of viewpoints in practice and demonstrates the ArchiMate tooling ideas. The last case description concerns the Dutch Customs and Tax Administration, where ArchiMate has been used in designing and analysing the technical infrastructure as part of a very large change programme. It shows how processes, applications, and technical infrastructure can be connected using the ‘service’ concept as a bridge, and visualised by applying the ArchiMate viewpoints. Finally, it shows the usage of quantitative analysis techniques to compute the application and infrastructural workloads.
