- 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 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
