For this purpose, we compared model quality and modelling costs of two sessions in five cases. The first was carried out in the usual way without tool support; in the second case we conducted the modelling session with the help of a collaborative modelling tool. We observed a marked decrease in modelling time in the second case and a rise in model quality.enBusiness Process ManagementInternational Journal of Organisational Design and Engineering1758-98001154144206
