Business process models are usually visualized using 2D representations. However, multiple attributes contained in the models such as time, data, and resources can quickly lead to cluttered and complex representations. To address these challenges, this paper proposes techniques utilizing the 3D space (e.g., visualizing swim lanes as third dimension). All techniques are implemented in a 3D process viewer. On top of showing the feasibility of the proposed techniques, the 3D process viewer served as live demonstration after which 42 participants completed a survey. The survey results support that 3D representations are well-suited to convey information on multiple attributes in business process models.
