  • Enterprise Architecture Modelling to Support Collaboration the Archimate Language As a Tool for Communication
    Enterprise Architecture modelling to support collaboration The ArchiMate language as a tool for communication Kurt Van der Veken 850834709 APRIL 2013 1 Enterprise Architecture modelling to support collaboration The ArchiMate language as a tool for communication Education: Business Process Management and IT Faculty: Computer Science Institute: Open Universiteit Commission board Executive examiner and first supervisor: dr. ir. F.J.M. Mofers (Frans) Second supervisor: dr. J.C.S.P. van der Woude (Jaap) Graduation coordinator: ir. H. Hofstee (Hans) Course: (T89317) Thesis Business Process Management and IT Student: 850834709 Booischot (Belgium), April 2013 2 Preface Few enterprises today have descriptive representations that depict how the enterprise works. Therefore, change can only be accommodated by trial and error. As complexity and the rate of change increase, risk of trial and error increases. Architecture provides the structure to predict the impact of change, reduce the risk and maintain enterprise viability in a changing environment. John Zachman This thesis has been submitted in partial fulfilment of the requirement for the degree of Master of Science in Business Process Management and IT (BPMIT). The BPMIT master program is an interfaculty master programme that combines courses from the faculty of Computer Science and the faculty of Management at the Open Universiteit Nederland (OU). I choose to graduate in the Enterprise Architecture discipline. The knowledge and insight obtained during the courses in the master program proved to be an excellent preparation for the graduation. Ever since I followed the course Information and Process Architecture in the master programme, I had a personal objective to get more skills and knowledge in the Enterprise Architecture discipline.

  • Enterprise Architecture for Information System Analysis
    Enterprise Architecture for Information System Analysis Modeling and assessing data accuracy, availability, performance and application usage PER NÄRMAN Doctoral Thesis Stockholm, Sweden 2012 TRITA-EE 2012:035 Industrial Information and Control Systems ISSN 1653-5146 KTH, Royal Institute of Technology ISRN KTH/ICS/R--12/01--SE Stockholm, Sweden Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy © Per Närman, September 2012, Copyrighted articles are reprinted with kind permission from El- sevier and Taylor & Francis. Universitetsservice US AB Abstract Decisions concerning IT systems are often made without adequate decision-support. This has led to unnecessary IT costs and failures to realize business benefits. The present thesis presents a framework for analysis of four information systems properties relevant to IT decision-making. The work is founded on enterprise architecture, a model-based IT and business management discipline. Based on the existing ArchiMate framework, a new enterprise architecture framework has been developed and implemented in a software tool. The framework supports modeling and analysis of data accuracy, service performance, service availability and application usage. To analyze data accuracy, data flows are modeled, the service availability analysis uses fault tree analysis, the performance analysis employs queuing networks and the application usage analysis combines the Technology Acceptance Model and Task-Technology Fit model. The accuracy of the framework’s estimates was empirically tested. Data accuracy and service performance were evaluated in studies at the same power utility. Service availability was tested in multiple studies at banks and power utilities. Data was collected through interviews with system development or maintenance staff.
