Collaborative process modeling with tablets and touch tables - A controlled experiment

Collaborative process modeling involves business analysts and subject matter experts in order to properly capture and document process knowledge. In this context, appropriate tool support is required to motivate these user groups to actively participate in collaborative process modeling. This paper presents a collaborative process modeling tool that enables the experts to create, visualize and evolve process models based on multi-touch devices (e.g., tablets and touch tables). In particular, users may edit process models on their tablets and share the created or changed process models with other team members on a common touch table. For this purpose, a sophisticated and intuitive interaction concept is provided. Furthermore, results of a controlled experiment, evaluating the influence the use of tablets has on collaborative process modeling based on touch tables, are presented. Altogether the experimental results emphasize the high potential of multi-touch tools for collaborative process modeling.
