- PublikationAuswahl der richtigen Wissensmanagement-Methoden(W. Gassmann, 2012) Hinkelmann, Knut; Witschel, Hans Friedrich [in: Blickpunkt KMU]Einerseits sind die Notwendigkeit für einen adäquaten Umgang mit der Ressource "Wissen" und der daraus resultierende potenzielle Gewinn für ein Unternehmen allgemein anerkannt. Andererseits entwickeln sich längst nicht alle Wissensmanagement-Projekte in der Praxis zu Erfolgsgeschichten. Im Gegenteil: selbst beim Einsatz vermeintlich bewährter Wissensmanagement-Strategien kommt es immer wieder vor, dass grossen Investitionen seitens eines Unternehmens am Ende kaum beobachtbare Verbesserungen gegenüberstehen. Häufigste Ursache hierfür ist die mangelnde Akzeptanz der implementierten Lösungen bei den Mitarbeitern.01B - Beitrag in Magazin oder Zeitung
- PublikationRefining Process Models through the Analysis of Informal Work Practice(2011) Brander, Simon; Hinkelmann, Knut; Hu, Bo; Martin, Andreas; Riss, Uwe; Thönssen, Barbara; Witschel, Hans FriedrichThe work presented in this paper explores the potential of leveraging the traces of informal work and collaboration in order to improve business processes over time. As process executions often differ from the original design due to individual preferences, skills or competencies and exceptions, we propose methods to analyse personal preferences of work, such as email communication and personal task execution in a task management application. Outcome of these methods is the detection of internal substructures (subtasks or branches) of activities on the one hand and the recommendation of resources to be used in activities on the other hand, leading to the improvement of business process models. Our first results show that even though human intervention is still required to operationalise these insights it is indeed possible to derive interesting and new insights about business processes from traces of informal work and infer suggestions for process model changes.04B - Beitrag Konferenzschrift

- PublikationA Graph-Based Recommender for Enhancing the Assortment of Web Shops(2015) Riesen, Kaspar; Witschel, Hans Friedrich; Galliè, Emidio [in: Proceedings of Workshop on Data Mining in Marketing DMM'2015]In this work, we consider a situation where multiple Providers (competitors) serve a common market, using a common infrastructure of sales channels. More speci cally, we focus on multiple web shops that are run by the same web shop platform provider. Our goal is to recommend new items to complement the assortment of a provider, based on user behaviour in the other shops of the same platform. For this new problem, we propose to capture information on how items sell together in a shared product co-occurrence graph. We then adapt known graph-based recommenders to the problem. Further criteria for ranking recommended items are derived as part of a case study conducted in the context of IT web shops. They are combined with the scores of the graph recommenders in a nal ranking function. We evaluate this function with data from our case study context and based on judgments of one shop owner. Our results show that a good ranking can be achieved, reflecting the needs of the shop owner.04B - Beitrag Konferenzschrift
- PublikationA Collaborative Approach To Maturing Process-Related Knowledge(2010) Witschel, Hans Friedrich; Hu, Bo; Riss, Uwe V.; Thönssen, Barbara; Hull, Richard; Mendling, Jan; Tai, Stefan [in: Business Process Management - Lecture Notes in Computer Science]We introduce a new approach supporting knowledge workers in sharing process-related knowledge. It is based on the insight that - while o ering valuable context information - traditional business process modelling approaches are too rigid and in exible to capture the actual way processes are executed. Therefore, business process models are made agile and open for changes during execution. To achieve this, the strict distinction between build time modelling and run time execution are softened and process activities are represented to the users in a way that allows for individual adaptations. That can be done by attaching resources, commenting on an issue or adding problems and solutions to an activity or process. In addition activities can be delegated or new (sub-)activities can be added. Thus, the model can adapt to the reality of actual process executions and valuable resources and experiences are proactively presented to users in the right context. A double-staged Approach is chosen to apply the model in the real application scenario of a university.04B - Beitrag Konferenzschrift
- PublikationOptimisation of Knowledge Work in the Public Sector by Means of Digital Metaphors(2010) Witschel, Hans Friedrich; Leidig, Torsten; Kaufmann, Viktor; Ostertag, Manfred; Brecht, Ulrike; Grebner, Olaf [in: Proceedings of I-KNOW 2010]Although most enterprises nowadays increasingly employ digital information management in all areas, there are still many organisations { e.g. in the Public Sector { where much of formal and informal information is documented on paper only. This work lays out the concept of a set of digital metaphors for entities in the "paper world" and argues that they will ease the adoption and acceptance of digital information and knowledge management solutions. We furthermore describe how the metaphors are linked with each other. We place a special focus on the relationship between informal, unstructured information and formally structured one, as well as on collaboration and knowledge sharing enabled by the metaphors. These aspects have been combined into a prototype that is described and illustrated in some detail.04B - Beitrag Konferenzschrift
