    Enterprise Modeling in Support of SOA Migration Analysis
    (Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 1, 2018) de Kinderen, Sybren; Kaczmarek-Heß, Monika
    This paper shows how enterprise modeling can support a Service-Oriented Architecture (SOA) migration analysis in terms of (1) IT infrastructure understanding, (2) identifying and refining candidate services by means of analyzing both the current IT infrastructure capabilities and business concerns, as well as (3) understanding how candidate services build on the current IT infrastructure. Based on requirements derived from a conducted literature study on SOA analysis and SOA migration projects, we identify the Multi-Perspective Enterprise Modeling (MEMO) method as a suitable language family to support a SOA migration analysis. Furthermore, we extend MEMO's language for IT infrastructure modeling, called ITML, with concepts central to SOA migration, and show how the modeling language can support key phases of a SOA migration project. We also provide a threefold evaluation of our SOA migration modeling approach by means of (1) application to documented SOA migration projects, (2) a scenario-based comparison with ArchiMate, another language that is a promising candidate for a SOA migration analysis, and (3) an assessment against the identified requirements. Finally, we discuss corresponding software tool support.

    Platform Provider by Accident
    (Business & Information Systems Engineering: Vol. 58, No. 3, 2016) Saarikko, Ted
    Recent years have witnessed the rapid emergence of digital technology as not just an enabler, but indeed a material basis for platform development. However, extant platform literature does not adequately address strategies related to digital platforms. Specifically, the notion of platform coring does not consider how a core is to be identified or the nature of a core in relation to entangled physical and digital materiality. This paper presents a single-case study of a digital platform for business-to-business services. Results suggest that rather than a specific platform element, the core of a digital platform may be described as a capability to harness the potential of digital technology. Furthermore, platform coring may be aided by adopting value propositions as a means to conceptualize the process of negotiating mutual benefit among platform stakeholders. This study contributes to the understanding of digital platform establishment as it addresses the notion of coring and the emergent process related to the distributed ontology of digital technology and a situated perception of value.
