Despite the availability of powerful mechanisms for security policy and accesscontrol, real-world information security practitioners—both developers and securityofficers—still find themselves in need of something more. We believe that this is thecase because available policy languages do not...

Most agree that enterprise architecture (EA) arti-facts include not only representation models, but also design principles [35]. While EA modeling and EA models are covered broadly in the EA state-of-the-art, design activity issues and design principles in particular are still neglected. While...

By the early twentieth century, Schumpeter had already stressed the importance of innovation for a sustainable development of enterprises. Innovation is especially important for information and com-munication technology (ICT) companies as their business model is based on rapidly changing...

A challenge in Information Systems Design Science Research (ISDSR) is the evaluation of constructedInformation Systems Design Theories. March and Smith (1995, p. 254) state that “significant difficulties… result from the fact that artifact performance is related to the environment in which...

In this paper, we propose an approach to transform modelsderived by applying the Design and Engineering Methodology for Organizations(DEMO) into an exchangeable format. DEMO is based ona founded theory, the -theory, and satisfies the requirements to be awell defined domain modeling methodology....

Based on an IEEE definition and its adaptation by The OpenGroup enterprise architecture (EA) is often defined as the fundamentalorganization of a company or government agency and theprinciples governing its design and evolution [16, 25]. Whiledesign representation issues like meta-modeling or...

Enterprise architecture management (EAM) is expected to providebusiness value by guiding the continuous development andtransformation of an enterprise. Based on the approach we strivefor constructing useful artifacts that guide the successful andsituational design of EAM. In order to do so we...

According to Kuhn, science and progress are strongly interrelated. Inthis paper, we define criteria of progress for design theories. A broad analysis of theliterature on information systems design science reveals that there is no consensuson the criteria of progress for design theories. We...
