Organizations are then faced with assessing which of the new functions drive value for them and which do not and so, how much they will benefit from an upgrade. The authors have developed a model for decision support. Various aspects of an upgrade can be assessed with the aid of software tools, such as analyses and evaluations of new functionality with respect to relevance, benefits, profitability, strategic goals and impact. In this article, we will present the portion of this model that can determine which functionality is relevant for an organization and to what extent. Our decision support model applies "reverse" system usage to identify which enterprise system functions are currently being used and which not. Based on usage data and pattern matching, we can determine which new functions add value for organizations. This helps businesses more easily determine which new functions are relevant to them and helps ensure that they continue to see a return on their often very expensive IT and IS investments far into the future.}, subject = {Betriebliches Informationssystem}, language = {en} } @inproceedings{HufgardSchulz2014, author = {Hufgard, Andreas and Schulz, Johannes}, title = {User activities in business processes - A system-based analysis}, series = {Proceedings of the 3rd International Conference on Information Systems Post-Implementation and Change Management}, booktitle = {Proceedings of the 3rd International Conference on Information Systems Post-Implementation and Change Management}, isbn = {978-989-8704-11-5}, pages = {215 -- 222}, year = {2014}, abstract = {Empirical data based on actual system use is in very short supply.
