    Applying soft systems methodology in enterprise architecture creation workshops
    (Enterprise modelling and information systems architectures (EMISA 2011), 2011) Nakakawa, Agnes; Bommel, Patrick van; Proper, Erik
    Lack of effective involvement of stakeholders is one of the main drawbacks of enterprise architecture initiatives. Ongoing attempts to overcome this involve using Collaboration Engineering to develop a collaboration process that enterprise architects can execute to facilitate collaborative sessions with stakeholders during architecture creation. However, a field study evaluation of this process revealed that it offered inadequate support for stirring vigorous and rigorous discussions during activities that required organizing and assessing problem or solution aspects that resulted from brainstorming activities. Since Soft Systems Methodology (SSM) helps to structure rational thinking about messy situations, its techniques can be adapted to supplement the design of the collaboration process with support for triggering discussions and creating a shared understanding and vision among stakeholders. This paper therefore presents a script that shows how this can be done, and discusses its evaluation in a real case.

    Architecture principles – A regulative perspective on enterprise architecture
    (Enterprise modelling and information systems architectures – concepts and applications, 2007) Bommel, Patrick van; Buitenhuis, Pieter; Hoppenbrouwers, Stijn; Proper, Erik
    Increasingly, organizations make use of enterprise architectures to direct the development of the enterprise as a whole and its IT portfolio in particular. In this paper we investigate the regulative nature of enterprise architecture. We aim to develop a fundamental understanding of the regulative needs that underly an enterprise architecture, and then take these needs as a starting point to arrive at requirements on the language (architecture principles) used to denote enterprise architectures. We furthermore discuss the process of formulating principles as well as their semantics.

    Integrating system dynamics with object-role modeling and Petri nets
    (Enterprise modelling and information systems architectures, 2009) Tulinayo, Fiona; Hoppenbrouwers, Stijn; Bommel, Patrick van; Proper, Erik
    The art of System Dynamics (SD) modeling lies in discovering and representing the feedback processes and other elements that determine the dynamics of a system. However, SD shows a lack of means for discovering and expressing precise, language-based concepts in domains. Therefore, we choose to use Object-Role Modeling (ORM) to add high quality formal conceptualization to SD modeling and Petri Nets (PNs) to bridge the gap between static ORM and Dynamic, flow-like aspects of SD. To achieve the integration of these methods, we take a step by step approach where we first identify the conceptual link between SD and ORM, then the key concepts used in these methods, which we later use to derive mappings, transition statements and elements. This helps us to better understand the underlying concepts, the connections between the model structure, and behavior in a sequential manner.
