This paper deals with the question of how software enabling participatory enterprise modeling on a multi-touch table should be designed. We will present a pre-selection of existing HCI patterns addressing the requirements which come along with collaboratively creating enterprise models on a shared workspace. Moreover, we examined a software prototype based on a task model and video analysis. The videos show participatory modeling sessions and give hint on frequent activities and deficiencies of the prototype. Based on our results, we will give recommendations of HCI patterns which should be applied when designing software tools for participatory enterprise modeling on multi-touch tables.
