Contributor Dietz, J.L.G.

In a utopia, every actor in an organization would be able to have an overview of his area of concern. Management would have a precise high level overview of all the business processes and their interaction with the information they manipulate through applications. They would exactly know which processes and actors are affected by a business decision. The operational employee would exactly know how the decisions he makes influence the organization as a whole. Unfortunately, misalignment is the biggest challenge of current organizations. The Rijkswaterstaat is no exception. To cope with the complexity the Enterprise Architecture and Consultancy (EAC) team of the RWS has adapted the RWS Enterprise Architecture Framework (RWS-EAF) as blueprint to structure the organization. This methodology combines the Integrated Architecture framework (IAF, which is the result of years of practical experience of Capgemini) with the DEMO methodology, a scientifically founded method for modeling the essence of an organization. The RWS-EA framework has already proven its value. During the Application Portfolio Rationalization project, the DEMO based business architecture has been linked to the applications used within the RWS. Still it proves to be a challenge to maintain a synergy within the enterprise architecture framework. As a result, the alignment between the business and the application/IT infrastructure is less than optimal. The thesis’s objective is to improve this connection by elaborating on an essential transitional stage in between; the Information Architecture. The products in the RWS-EA are analyzed by positioning them in a DEMO perspective. An assessment framework created during research is consulted to qualify the current Information Architecture of the RWS. To further synchronize the RWS organization, UPP process models created by Beheersorganisatie Processen en Systemen (BPS) of the RWS are included by using a methodology adopted from previous research. A DEMO based methodology which allows development of products for the Business, Information and Application organization is demonstrated with the use of a case study. The most notable models are the Process Structure Diagrams (PSD) which satisfies the DEMO-3 specification and the Natural BID models which are based upon a proposal of the EAC team. The cross relationship between the products and their place within the RWS-EAF are depicted. The proposed design of the Information Architecture is qualified to the assessment framework. Some final thoughts are given about the methodology as developed, the integration in the architectural tools and the possibilities for further improvement in future iterations.
