- ZeitschriftenartikelEnterprise Architecture in Enterprise Engineering(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 3, Nr. 1, 2008) Hoogervorst, Jan A.P.; Dietz, Jan L.G.Originating from quite different fields of theory and practice, the terms "Enterprise Ontology" and "Enterprise Architecture" currently belong to the standard vocabulary of those professionals who are concerned with (re)designing and (re)engineering enterprises, thereby exploiting modern information and communication technologies for innovating products and services as well as for optimizing operational performance. Because of the inherent characteristics of modern enterprises, often operating within networks of cooperating enterprises, the task of these professionals can rightly be characterized as having to master unprecedented high complexity. The statement, put forward in the paper, that the current notion of Enterprise Architecture does not offer satisfactory help and thus need to evolve into an effective conceptual tool, is clarified in a historical context. In order to let Enterprise Architecture become a sensible, effective notion, complementary to Enterprise Ontology, it is proposed to define it conceptually as normative restriction of design freedom, and operationally as a coherent and consistent set of design principles. The new, evolved notion of Enterprise Architecture is clarified and illustrated using a case example.
- ZeitschriftenartikelA Framework for Clarifying Service-Oriented Notions - How to Position Different Approaches(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 5, Nr. 1, 2010) Terlouw, Linda I.; Dietz, Jan L.G.Definitions on Service-Oriented Architecture (SOA) and Service-oriented Design (SoD) are often not clear or even contradictory, which makes it hard to compare the various methodologies. We apply the Generic System Development Process (GSDP), a conceptual framework for developing systems of any kind, and specialise it for service-orientation. Using the resulting Service-Oriented Development Process, we position seven state-of-the art methodologies for service-orientation based on two criteria. One is the coverage of the system development process. The other criterion is the depth in which each of the development phases are dealt with.
