In this work, a visual analytics tool is developed which enables automatic analysis of processes, which are defined by the user, of monitoring systems. This tool provides reports of the performance and sequence of process steps and allows a more detailed analysis of user interactions. Based on technologies of visual analytics and information visualization, data sets can be analyzed and presented visually for deeper analysis. This includes a directed node-link diagram, that represents the process model and diagrams for metadata such as the performance of each step.
The objective is to be able to handle even large amounts of data and to compare a state of the process with the desired process state. The incoming data are event data consisting of logs from events which represent process steps used in a process containing a timestamp and other information like e.g. money or duration. The problem which has to be solved is to handle the information extracted from event data and to find complex, direct and indirect relations between process steps by giving an overview using a node-link diagram with weighted edges to represent the transitions from one process step to another and providing interaction techniques. Additional the information has to be analyzed according to chosen indicators (e.g. duration or money) and to compare different types of process runs with each other, e.g. separating complete and incomplete runs, to possibly find these relations which can be indicators for an incomplete run. As a result the tool gives the ability to choose different runs to compare them and simultaneously compares the chosen indicators. Furthermore, the tool was evaluated to find out, if it is possible to solve this problems by using this tool.
