Pintus A., Paterṇ F., Santoro C. Modelling user interactions in web service-based business processes. In: WEBIST 2010 - 6th International Conference on Web Information Systems and Technologies (Valencia, Spain, 7-10 April 2010). Proceedings, vol. 2 pp. 175 - 180. INSTICC Press, 2010.
This paper presents a methodology that defines a model-based approach in composing User Interfaces for Business Processes based on Web service technology. The core concepts of the methodology are represented by an integration of modern task model notations developed in the HCI area, such as ConcurTaskTrees, with a mainstream notation for Business Process modelling (BPMN) developed in the workflow/business process area. The main advantage is to obtain thorough support in designing complex interactive business applications able to flexibly compose Web services and obtain meaningful associated user interfaces which can be not only Web interfaces but also extended to a multi-modal fruition. The proposed methodology allows a collaborative work between business process modellers and user interface modellers remaining open to iterative refinements. In this paper we also briefly compare the considered notations and discuss an example application of the proposed method.
