Project management information systems have changed considerably over the last decade. They no longer focus on scheduling and resource management alone. Instead, they have become comprehensive systems that support the entire life-cycle of projects, project programs, and project portfolios. In this context, project-oriented organizations are facing a new challenge: the design, implementation, and operation of project management information systems have become increasingly complex. Numerous processes have to be considered, diverse stakeholder interests taken into account, and corresponding software systems selected. The reference information model (RefModPM) presented in this article addresses this challenge and aims to accelerate the set-up of project information systems. RefModPM was developed with the help of 13 domain experts from German and Swiss enterprises. Furthermore, it is based on an analysis of 28 commercial project management software systems. RefModPM has already been applied in several projects and is the basis of the forthcoming German DIN norm for a standardized project management data model.
Project management information systems (PMIS) are widely regarded as an important building block in today’s project management . The nature of these systems has changed considerably during the last decade; they are, in fact, still developing from single-user/single-project management systems to complex, distributed, multi-functional systems that no longer only cover project planning . Information systems research has to date only partly reflected this PMIS evolution. Typical fields of research are (1) algorithms in respect of operation research problems related to project management (e.g. ,  and ), (2) the assessment and comparison of commercial project management solutions and corresponding assessment frameworks (e.g. ,  and ), (3) the development of prototypes to test new kinds of functionality (e.g. ,  and ), and (4) research into the usage of project management software systems (e.g. ,  and ). Two specific problems are very rarely addressed: PMIS are become increasingly complex. Therefore, firstly, information system designers are facing a growing number of business processes that have to be supported with project management software. Secondly, information system users have difficulties in setting up corresponding organizational systems and selecting corresponding software products. An expert survey by Meyer indicates that only in approximately 20% of cases do organizations have information systems in place that support multi-project programme and portfolio management [13, p. 9]. In contrast, approximately 99% of organizations use information systems for scheduling and time management [13, p. 13]. The potential of existing PMIS is clearly not being exploited at all. This article addresses these issues by presenting a reference information model for enterprise-wide project management that covers all project management processes that are related to planning, controlling, and coordinating projects (RefModPM). The model can be used for the design of project management software, the set-up of the surrounding organizational system, as well as for the definition of software requirements that are essential to select a commercial project management software system. RefModPM covers both single-project management and multi-project management. It is based on a single, uniform information system architecture called M-Model and makes use of the Unified Modeling Language (UML) Version 2. This paper is structured as follows: section two describes the conceptual and terminological foundation of this article and presents a review of existing approaches to reference modelling in respect of PMIS. A brief description of the research design and the sources of the construction process are provided in section three. Section four outlines the architecture of the reference model, the M-Model. A more detailed exemplary excerpt of the reference model is presented in section five, which is then compared to the modelling approaches presented by other authors. In section six, examples that illustrate the model’s application are described, followed by concluding remarks that summarize the paper.

The discussion of the model excerpt indicates that RefModPM goes beyond the scope of previous reference models. This is not surprising, since RefModPM uses some ideas from previous work and extends it according to additional requirements. Table 5. demonstrates the extent to which RefModPM represents significant research progress in the field of PMIS reference models, since it • has a significantly wider scope, covering not only project planning and execution, but also the initiation and termination phase, • has been designed to serve both single and multi project management purposes, and • covers all functional areas of PMI’s PMBOK. • Moreover, the research methodology underlying the model construction and evaluation is presented. The complete reference model has been made available to the public in book form.
