This paper proposes a framework and tool for conducting laboratory experiments with collaborative systems. The framework and tool seek to control a large number of experimental conditions, while obtaining fine-grained log data about the individual and collaborative activities. Furthermore, the proposed framework and tool allow reusing voice communication(More)
Mobile computing has experienced a rapid growth and there are nowadays many applications being developed. According to the literature, many of these applications are designed for collaborative work or learning and share the same requirements: they implement a peer-to-peer communication architecture, there are subgroups inside the group of participants which(More)
We describe the design of a mobile collaborative tool that helps teams managing critical computing infrastructures in organizations, a task that is usually designated Business Continuity Management. The design process started with a requirements definition phase based on interviews with professional teams. The elicited requirements highlight four main(More)
A proposal of a method to assess awareness support is made. This proposal is intended for the use of collaborative applications developers at any time during development. It consists of a checklist. It is made with the inclusion of design elements obtained by the analysis of Quality Assurance ideas applied to collaborative systems. The proposal is(More)
When organizations face unforeseen emergency situations its members often resort to unstructured crisis management activities in order to overcome the problems. Researchers have noted that a common activity in these scenarios is the construction of a shared awareness of the situation in order to collaboratively identify the actions required to be carried on(More)
Organizations orchestrate work along a continuum of structured and unstructured activities. Particularly in emergency situations and crisis management scenarios, the organization’s procedures and information systems may not cope with the information and collaboration requirements imposed by the dynamic of unplanned situations, emerging such unstructured(More)
We developed a platform supporting the evaluation of teamwork. The platform logs oral communications, collaborative tool usage and simulated physical action in the work environment. The paper brings forward observations derived from a comprehensive study of maintenance teams operating simulated network infrastructures. As positive results, we highlight that(More)
