    Developing web applications for small and medium-sized enterprises – an experience report
    (Informatik 2004 – Informatik verbindet – Band 1, Beiträge der 34. Jahrestagung der Gesellschaft für Informatik e.V. (GI), 2004) Aleksy, Markus; Gitzel, Ralf; Schwind, Michael
    In this paper we describe one of the authors' experiences working for an IT service provider in an SME environment. The paper starts with an analysis of the factors typical for the SME business environment and discusses the typical shortcomings resulting from this constellation. Finally, a theory is proposed why the potential of object-oriented methods is not yet realized in the SME environment as perceived in this experience report. While not an empirical study, the paper tries to provide some material for discussions and motivation for specialized approaches for SME software development.

    Industrial Services as a Research Discipline
    (Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 11, Nr. 4, 2016) Gitzel, Ralf; Schmitz, Björn; Fromm, Hansjörg; Isaksson, Alf; Setzer, Thomas
    Services in the industrial sector—commonly referred to as industrial services—are an important source of profit, differentiation and future growth for their providers. This sector includes industries such as heavy equipment manufacturing, energy production, chemical production and oil and gas. Despite its importance, neither the term industrial service(s) nor its concrete subareas are unambiguously defined. The goal of this paper is to motivate research which addresses the challenges currently faced in the industrial sector with regard to service. For this purpose, we review existing definitions of industrial services and identify the services in scope as well as the scientific disciplines that can contribute. The main part of the paper is a list of relevant current and future challenges which have been encountered by the authors during their daily practice.
