    Multi-Level Design of Process-Oriented Enterprise Information Systems
    (Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 15, Nr. 10, 2022) Ulrich Frank, Tony Clark
    This paper presents prototypical multi-level models of two uses cases. They comprise models of business processes and of models that represent the context required to execute a business process. On the one hand, the context consists of the organizational units that are responsible for the execution of processes. They are represented by a model of organizational structures. On the other hand, the context includes the artifacts that are needed or manipulated by processes. The models serve to demonstrate the specific power of multi-level modeling. First, they integrate models on higher levels, which correspond to domain-specific modeling languages, with those on lower levels. In addition, models are supplemented with objects on L0 to demonstrate how these can be integrated. The models are executable without the need to generate code, since models and corresponding program code share the same representation, thus demonstrating the possibility of advanced application system architectures, which allow users to navigate a comprehensive representation of the system they work with at runtime. The presentation of the models is supplemented with a general evaluation of multi-level concepts. The design of the models was inspired by the EMISA process challenge. Therefore, they are evaluated against the requirements defined with the challenge. In addition, a challenge is discussed that goes beyond the challenge, that is, the design of multi-level models of behavior.

    RefModPM: A Conceptual Reference Model for Project Management Information Systems
    (Wirtschaftsinformatik: Vol. 50, No. 2, 2008) Ahlemann, Frederik; Riempp, Gerold
    Project management information systems have changed considerably in the last decade. Today they go far beyond traditional scheduling as well as resource management. These systems have become comprehensive information systems (IS) that support the entire life cycle of projects, project programmes and project portfolios. In this context, project-oriented organizations face a new challenge: the design, implementation and operation of such information systems has become increasingly complex, since numerous processes have to be considered, diverse stakeholder interests taken into account and corresponding software systems selected. The reference model for project management IS (RefModPM) presented here addresses these challenges and aims to support corresponding implementation projects. This article introduces RefModPM by discussing its construction process and evaluation, as well as providing an overview of its architecture and presenting one part of the reference model in detail.ZusammenfassungDer Artikel stellt ein konzeptionelles Informationssystem-Referenzmodell für das Projektmanagement vor (RefModPM). Hierzu wird zunächst auf den Konstruktions- und Evaluationsprozess eingegangen, in dessen Rahmen RefModPM entwickelt wurde. Dann erfolgt eine überblicksartige Vorstellung der Referenzmodellarchitektur. Abschließend wird ein Modellausschnitt im Detail diskutiert.
