The quality of Business Process Models is an increasing concern as enterprise-wide modeling initiatives have to rely heavily on non-expert modelers. Quality in this paper can be directly related to the actual usage of these process models, in particular to their understandability and modifiability. Since these attributes of a model can only be assessed a posteriori, it is of central importance for quality management to identify significant predictors for them. A variety of structural metrics have recently been proposed, which are tailored to approximate these usage characteristics. In this paper, the authors address a gap in terms of validation for metrics regarding understandability and modifiability.
