What Makes Process Models Understandable?
Despite that formal and informal quality aspects are of significant importance to Business Process Modeling, there is only little empirical work reported on process model quality and its impact factors. In this paper, the authors investigate understandability as a proxy for quality of process models and focus on its relations with personal and model characteristics. They used a questionnaire in classes at three European universities and generated several novel hypotheses from an exploratory data analysis. Furthermore, they interviewed practitioners to validate their findings.
