In this paper, business processes modeling is done by trained method experts. Domain experts are interviewed to elicit their process information but not involved in modeling. The authors created a haptic toolkit for process modeling that can be used in process elicitation sessions with domain experts. They hypothesize that this leads to more effective process elicitation. This paper brakes down \"Effective elicitation\" to 14 operationalized hypotheses. They are assessed in a controlled experiment using questionnaires, process model feedback tests and video analysis.
