    A Method for Developing Generic Capability Maps
    (Business & Information Systems Engineering: Vol. 65, No. 4, 2023) Van Riel, Jonas; Poels, Geert
    Capability-based management is an approach for strategy formulation and implementation that is rooted within the enterprise architecture discipline and founded on managerial theories. The main instrument of capability-based management is the capability map, which provides a structured and hierarchical overview of an organization’s capabilities. At a sufficiently high level of abstraction, organizations within the same industry or societal sector are managed based on capabilities that can be described using a generic capability map. While industry/sector-specific capability maps are used in consultancy practice, knowledge of how to develop such generic capability maps is lacking in the academic literature. Therefore, the paper addresses the question of how a generic capability map for organizations within the same industry/sector can be developed. Professional sport clubs were used as the application field for the design science research. The research was executed in collaboration with three major, premier league Belgian clubs that operate in the highest tier of their respective professional sport competition. After different iterations of joint development and evaluation activities with these clubs, the final design of a generic capability map was successfully obtained. Through reflection and learning from this process, the paper formulates the procedural knowledge that was gained in the study as prescriptions that can be used as general steps of a method for creating other industry/sector-specific capability maps. This outline of a method for developing generic capability maps is an original contribution to the enterprise architecture discipline.

    Bridging requirements engineering and business process management
    (Software Engineering 2009 - Workshopband, 2009) Decreus, Ken; Kharbili, M. El; Poels, Geert; Pulvermueller, Elke
    Requirement elicitation is one of the earliest phases of a requirement engineering lifecycle. However, even though years of research have gone into seeking machine support for requirements engineering, the methods used are still highly manual and the vision of automatic transfer of business analysis requirements into IT systems supporting the business is still far from reach. On the other hand, incepting knowledge for creating AS-IS business processes in enterprise models has been recognized as a hard problem. In the context of a process centric organization, we propose an approach to create AS-IS business process models by automatically transferring requirements to the business process layer. Our aim is to enable carrying business requirements, goals and policies from an inception layer to the operational business process management layer. We place our research in the context of a semantic business process management platform (SUPER) as the support to exploit the output of our research. This paper grounds this research work and proposes a research design for requirement elicitation for producing early-phase business process models that are nearer to the business analysis layer.

    A Domain-specific Modeling Technique for Value-driven Strategic Sourcing
    (Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 8, 2018) Rafati, Laleh; Roelens, Ben; Poels, Geert
    Strategic sourcing recognizes that procurement should support a firm’s effort to achieve its long-term objectives. In particular, procurement needs to be a cross-functional end-to-end process inside the organization that is oriented towards value creation within the company and between the company and its partners in the value chain. The main challenge to the implementation of value-driven strategic sourcing is the lack of instruments that are characterized by analytical rigor and robustness in the identification of strategic sourcing options to achieve strategic goals. Therefore, this research aims to develop a domain-specific modeling technique founded on the Service-Dominant Logic which focuses on the systemic exploration of sourcing alternatives and emphasizes the delivery of value to achieve desired outcomes. This paper reports on a first cycle of Design Science Research which includes the demonstration and the evaluation of the value and utility of the modeling artefacts by means of a case study about IT outsourcing in the healthcare industry.

    Mixed-Paradigm Process Modeling with Intertwined State Spaces
    (Business & Information Systems Engineering: Vol. 58, No. 1, 2016) Smedt, Johannes; Weerdt, Jochen; Vanthienen, Jan; Poels, Geert
    Business process modeling often deals with the trade-off between comprehensibility and flexibility. Many languages have been proposed to support different paradigms to tackle these characteristics. Well-known procedural, token-based languages such as Petri nets, BPMN, EPC, etc. have been used and extended to incorporate more flexible use cases, however the declarative workflow paradigm, most notably represented by the Declare framework, is still widely accepted for modeling flexible processes. A real trade-off exists between the readable, rather inflexible procedural models, and the highly-expressive but cognitively demanding declarative models containing a lot of implicit behavior. This paper investigates in detail the scenarios in which combining both approaches is useful, it provides a scoring table for Declare constructs to capture their intricacies and similarities compared to procedural ones, and offers a step-wise approach to construct mixed-paradigm models. Such models are especially useful in the case of environments with different layers of flexibility and go beyond using atomic subprocesses modeled according to either paradigm. The paper combines Petri nets and Declare to express the findings.

    The Development and Experimental Evaluation of a Focused Business Model Representation
    (Business & Information Systems Engineering: Vol. 57, No. 1, 2015) Roelens, Ben; Poels, Geert
    Business models (BM) are the central concept to understand the business logic of an organization. Enterprise modeling contributes to the conceptualization of BMs by providing explicit representations. A proper BM representation helps to increase the understanding and communication about the underlying knowledge for the stakeholders within a company. However, the existing enterprise modeling languages have a different and partial focus on the BM concept due to their various backgrounds. This prevents the large-scale adoption of these representations in practice. Therefore a focused BM viewpoint is developed, which explicitly facilitates the understanding about the underlying BM components. To this end, existing diagrams of the value delivery modeling language were adapted to prescriptions of the physics of notations, which is a normative theory for cognitive effectiveness of diagrammatic representations. The effect on the understanding was evaluated by an experiment with 93 master students. The results confirm the research hypothesis that the new BM viewpoint increases the understanding of the modeled BM components.
