Master's Thesis

Last month I have completed my master's thesis which can be downloaded here.


In business process management, the first step toward improvement of processes is As-Is analysis of existing processes before working towards a To-Be situation. Process mining is part of this As-Is analysis and gives insight into various aspects of processes through the mining of events recorded by a system in the form of an event log. This enables discovery of the process as it actually is. Depending on how much detail an event log contains, observations can be made about the process itself, participating resources, the cases in the process and time aspects. This information is used to improve the process. For many businesses, cost reduction is also an important motivator for change. Since most, if not all, sort of change affects processes within a business, cost reduction and process improvement are inseparable from each other. This work addresses the neglected role of cost reduction in process mining. Or, to put it differently, to support management accounting decisions on cost reduction through the use of cost-aware process mining. Taking into account existing cost reduction techniques within management accounting and extending the process mining tool ProM, this work proposes an architecture to support cost-awareness in process mining, and a first implementation of this architecture.
