Previous research has put forward various metrics of business process models that are correlated with understandability. Two such metrics are size and degree of (block-) structuredness. What has not been sufficiently appreciated at this point is that these desirable properties may be at odds with one another. This paper presents the results of a two pronged study aimed at exploring the trade-off between size and structuredness of process models. The first prong of the paper is a comparative analysis of the complexity of a set of unstructured process models from industrial practice and of their corresponding structured versions. The second prong is an experiment wherein a cohort of students was exposed to semantically equivalent unstructured and structured process models.
