FROM CONCEPTUAL PROCESS MODELS TO RUNNING SYSTEMS: A HOLISTIC APPROACH FOR THE CONFIGURATION OF ENTERPRISE SYSTEM PROCESSES Alexander Dreiling, Michael Rosemann, Wil MP van der Aalst, Wasim Sadiq. Decision Support Systems. May 2008. Vol. 45, Iss. 2; pg. 189 Abstract (Summary) This paper proposes a method which aims at increasing the efficiency of enterprise system implementations. First, we argue that existing process modeling languages that feature different degrees of abstraction for different user groups exist and are used for different purposes which makes it necessary to integrate them. We describe how to do this using the meta models of the involved languages. Second, we argue that an integrated process model based on the integrated meta model needs to be configurable and elaborate on the enabling mechanisms. We introduce a business example using SAP modeling techniques to illustrate the proposed method. [PUBLICATION ABSTRACT]
REPRESENTING PART-WHOLE RELATIONS IN CONCEPTUAL MODELING: AN EMPIRICAL EVALUATION Graeme Shanks, Elizabeth Tansley, Jasmina Nuredini, Daniel Tobin. MIS Quarterly. Sep 2008. Vol. 32, Iss. 3; pg. 553
Abstract (Summary) The part-of construct is a fundamental element of many conceptual modeling grammars that is used to associate one thing (a component) with another thing (a composite). Substantive theoretical issues surrounding the part-of construct remain to be resolved, however. For instance, contrary to widespread claims, some researchers now argue the relationship between components and composites is not always transitive. Moreover, how the part-of construct should be represented in a conceptual schema diagram remains a contentious issue. Some analysts argue composites should be represented as a relationship or association. Others argue they should be represented as an entity. In this paper we use an ontological theory to support our arguments that composites should be represented as entities and not relationships or associations. We also describe an experiment that we undertook to test whether representing composites as relationships or entities enables users to understand a domain better. Our results support our arguments that using entities to represent composites enables users to better understand a domain. [PUBLICATION ABSTRACT]
