  The construction of business process models has become an important requisite
in the analysis and optimization of processes. The success of the analysis and
optimization efforts heavily depends on the quality of the models. Therefore, a
research domain emerged that studies the process of process modeling. This
paper contributes to this research by presenting a way of visualizing the
different steps a modeler undertakes to construct a process model, in a
so-called process of process modeling Chart. The graphical representation
lowers the cognitive efforts to discover properties of the modeling process,
which facilitates the research and the development of theory, training and tool
support for improving model quality. The paper contains an extensive overview
of applications of the tool that demonstrate its usefulness for research and
practice and discusses the observations from the visualization in relation to
other work. The visualization was evaluated through a qualitative study that
confirmed its usefulness and added value compared to the Dotted Chart on which
the visualization was inspired.
