Awareness to users is a valuable feature of a collaborative system. Therefore, the designers of a system of this type may find it useful to receive hints on the awareness support provided by the system when it is under development or evolution.

This paper discusses the role of PDA in the meeting environment. Three fundamental design issues are raised: PDA as mobile devices, CSCW devices and coordination devices. The research work described in this paper is focused on the coordination facet. The paper proposes three levels of detail to characterize meetings as coordination mechanisms and ascertain(More)
This article presents a framework for the development of hypermedia systems, based on systematic modelling approaches. These introduce models at three abstraction levels (conceptual, navigation and presentation). An object-oriented approach, UWE, proposing UML extensions was adopted. The work described in this paper reports a solution for an integrated and(More)
This paper discusses the negotiation-collaboration process: a binomial process mixing collaboration, negotiation and argumentation. We applied the negotiation-collaboration process to Formal Technical Reviews, commonly adopted to verify the functional specification of software. We developed a groupware tool demonstrating the dynamic of the(More)
This paper proposes a novel architectural framework handling effective unexpected exceptions in workflow management systems (WfMS). Effective unexpected exceptions are events for which the organizations lack handling strategies. Unstructured human interventions are necessary to overcome these situations, but clash with the type of model control currently(More)
