Assessing Modifiability in Application Services Using Enterprise Architecture Models - A Case Study

Enterprise architecture has become an established discipline for business and IT management. Architecture models constitute the core of the approach and serve the purpose of making the complexities of the real world understandable and manageable to humans. EA ideally aids the stakeholders of the enterprise to effectively plan, design, document, and communicate IT and business related issues, i.e. they provide decision support for the stakeholders. However, few initiatives explicitly state how one can analyze the EA models in order to aid decision-making. One approach that does focus on analysis is the Enterprise Architecture Modifiability Analysis Tool. This paper suggests changes to this tool and presents a case study in which these have been tested. The results indicate that the changes improved the tool. Also, based on the outcome of the case study further improvement possibilities are suggested.
