Move Change Patterns

To improve process model quality, process change patterns offer promising perspectives. Usually, they combine multiple change primitives (e.g., to add or delete nodes and edges respectively) to high-level change operations. Furthermore, existing pattern implementations (i.e., process modeling tools) often enable a  correctness-by-construction principle by providing only those change patterns to the process modeler, which ensure that a given process model remains sound after applying the desired model transformations.

The goal of this experiment was to investigate the impact of  different change pattern sets on problem solving effectiveness and problem solving efficiency. Additionally, we were interested in how far the available pattern set impacts the subjective perception of process modelers regarding change pattern usage.
