Informationsmodelle werden neben Softwareentwicklung und Geschäftsprozessmanagement vor allem auch für die Einführung von Standardsoftware eingesetzt. Der vorliegende Beitrag untersucht die gegenwärtige Praxis des Einsatzes von Informationsmodellen bei der Softwareeinführung. Die Untersuchung zeigt, Information models are an established instrument to handle the complexity of information systems. In addition to software development and business process management the implementation of packaged software is one of the major application domains of information models. This contribution investigates through an explorative study, how information models are currently used in the context of packaged software implementation. Object of investigation is the implementation of billing software within utility companies. The study indicates that most companies of the sample applied information models within their implementation projects. Process and data models are more common than other models. However, only a minor part of the companies used dedicated modeling tools for the development and management of the models. The major application domain of information models was the configuration of the software, whereas model based software selection was from subordinate interest. The majority of companies who have applied information models will do this in future projects again [ABSTRACT FROM AUTHOR]
