User experience-based evaluation of open source workflow systems: The cases of Bonita, Activiti, jBPM, and Intalio

The task of selecting a workflow system becomes more and more complex and risky. For this reason, organisations require a broad, and a clear vision of which workflow engines are, and will continue to be, suitable for changing requirements. This paper presents a user experience based evaluation model for workflow systems to analyse, compare, and select business process management modelling and enactment systems according to user specific requirements. After the description of the underlying worflow system evaluation model itself, we experiment it to assess criteria satisfaction on four open source workflow systems Bonita, Activiti, jBPM, and Intalio.
