Using System Dynamics Models to Understand and Improve Application Landscape Design

Application landscape design has become a key challenge for enterprises. For further exploration of related enterprise architecture benefits establishing shared mental models among all application landscape designers is required, i.e. architectural thinking. Thus, to complement existing approaches by modeling human behavior and decision effects which form implicit application landscape evolution principles, we propose the use of System Dynamics. We derive five guidelines from literature for developing a corresponding method. To exemplify the approach, a concrete causal loop diagram on the topic of technological standardization is presented. A subsequent evaluation based on expert interviews demonstrates the model content validity as well as the modeling method\u27s suitability to foster communication among different communities of practice
