Business Process Modeling (BPM) is used extensively over the last years to represent business processes in an universal and formal way in todays companies. The process models are providing a common understanding of a companys business processes and enable the discovery of improvement opportunities and thereby create added value for the company. Due to this critical role for managing business processes, process modeling becomes more and more an important task and therefore it is necessary to evaluate the quality of process model (PM)s from different viewpoints. Recently several experiments have been conducted, in which the creation of business PMs has been studied (also denoted as Process of Process Modeling (PPM)) instead of analyzing and focusing on final process models. To develop a comprehensive understanding, different visualizations for the PPM have been developed. For example the visualization Modeling Phase Diagram (MPD), which is used to illustrate the evolution of a PM, whereby the modeling phases are used as abstractions. This thesis builds upon this research and extends the existing state-of-the-art by categorizing and anaylzing interactions of PPM instances collected with Cheetah Experimental Platform (CEP) in a systematic manner. Additionally, to make qualified assertions and for further analysis, a new visualization of PPM instances, named Modeling Steps Diagram (MSD), has been developed. In this visualization, the step types were used as abstraction, which will help to identify different activities within the PPM and also might help for the observation and categorization of modeling behavior. In conclusion, this conducted analysis will help to gain a deeper understanding of the Process of Process Modeling and should help to support modelers in creating process models of higher quality.
