Hierarchy in Declarative Business Process Models

This experiment is examining hierarchy in declarative business process models. In particular, we elaborated hierarchical declarative business process models and semantically-equivalent declarative business process models without hierarchy. Participating subjects had then to answer questions about particular aspects of the models. To analyse the answers, we use questionnaires and think-aloud technique.

Material

The experiment makes use of repeated measurement, hence we defined two experimental groups: group 1 received the flat model first (see questionnaire here), group 2 started with the hierarchical model (see questionnaire here) .

To support subjects during the experiment and to avoid that constraints were misunderstood, subjects received this handout and this introduction before the experiment, and this sheet with constraints during the experiment.
