Augmenting process elicitation with visual priming: An empirical exploration of user behaviour and modelling outcomes. (December 2016) - Harman, Joel
Abstract: Business process models have become an effective way of examining business practices to identify areas for improvement. While common information gathering approaches are generally efficacious, they can be quite time consuming and have the risk of developing inaccuracies when information is forgotten or incorrectly interpreted by analysts. In this study, the potential of a role-playing approach to process elicitation and specification has been examined. This method allows stakeholders to enter a virtual world and role-play actions similarly to how they would in reality. As actions are completed, a model is automatically developed, removing the need for stakeholders to learn and understand a modelling grammar. An empirical investigation comparing both the modelling outputs and participant behaviour of this virtual world role-play elicitor with an S-BPM process modelling tool found that while the modelling approaches of the two groups varied greatly, the virtual world elicitor may not only improve both the number of individual process task steps remembered and the correctness of task ordering, but also provide a reduction in the time required for stakeholders to model a process view. Abstract : Highlights: Implemented a virtual world (VW) role-play tool to assist with process elicitation. Performed A/B experiment comparing developed VW with standard 2D modelling tool. VW group specified more tasks, made fewer errors and took significantly less time. VW group referred to similar actions/objects more consistently with their naming. Behavior of VW participants consistent with identified traits of better modellers.
