A widely established way of determining the effectiveness and efficiency of modeling techniques is by way of representational analysis. The purpose of this paper is to comparatively assess the outcomes of representational analyses of twelve popular process modeling techniques in order to provide insights into the extent to which the representational capabilities of process modeling techniques differ between each other and evolve over time, measured by the extent to which the techniques are able to facilitate complete and clear descriptions of real-world domains. Our research shows that, over time, process modeling technique have indeed increased their scope of coverage; however, this increased effectiveness of the techniques comes at the extent of increased complexity and ambiguity in the use of these techniques.
