Control-Flow Representation of Business Processes - An Empirical Comparison of Connectors vs. Token Game

A number of process modelling notations use connectors for the representation of the control-flow while others apply the token game. There are number of good arguments in favour as well as against each to these two ways of representing the control-flow. This contribution describes the results of an empirical comparison of these two approaches from the end-used perspective. The overall outcome of the experiment supports the assumption that notations applying connectors are superior to the token game-based notations in terms of end-user comprehension at the conceptual modelling level.
