In the most of today's organizations, tasks are performed in groups in which the negotiation is necessary to arrive at a result. During the search for solutions that are accepted by all, are carried out sessions of "brainstorm" and meetings involving groups, possibly located in different places. This work aims to increase the existent knowledge about the dynamics of the binomial "negotiation-cooperation,"...
Group participants can diverge regarding awareness information comprehension initially available in the shared workspace. In addition, such information can become irrelevant or insufficient throughout the interaction, resulting in a loss of context. The goal of this work is to analyze the risk factors related to the context loss as well as the context mismatch in groupware. In order to illustrate...
The competitive forces that drive organizations' development have brought great interest to innovation, as the information content of products, processes, and means of production has become the great differentiator among companies. Technological progress has made the innovation process dependent on the interaction of interdisciplinary teams which can be geographically dispersed. The need for communication...
This paper points to problems in the joint use of the use case model and the domain model in the system requirements definition phase. It proposes a specialization of use cases called info cases, from which a domain model can be derived. Semi-formal rules are presented for the derivation, showing evidence of the integration between these models.
Business process modeling is expensive and time consuming. It depends very much on the elicitation method and the person in charge. The model needs to be shared in order to promote multiple perspectives. This paper describes a group storytelling approach as an alternative to the traditional individual interviews to elicitate processes. The form of information gathering is the stories told by processes'...
In emergency response organizations with very limited resources, information technologies are not adequately explored. In such organizations, the simple adoption of new information technologies is not productive, as their efficient use depends on many other interrelated technologies. This work describes a model to help understanding these interrelationships. The model allows the cooperative evaluation...
Many approaches to work analysis have been proposed so as to enhance the requirements elicitation for systems design. However, systems delivered at dynamic, complex and socio-technical workplaces, have still failed at satisfying the needs of users successfully, mainly because they are unable to support activities entirely, especially those related with cognition and collaboration. This paper describes...
The requirements elicitation of a system is a complex task. The different viewpoints and the need for negotiation make this stage of the software development process risky and susceptible to failures. The traditional elicitation approach based on interviews and questionnaires do not help. This paper proposes an approach founded on collective knowledge to progressively build the system requirements...
Knowledge management has become a prominent subject for organizations, but often characterization and treatment of the information that flows in a well-defined design work process are muddled. We argue that context is the fundamental information resource for better understanding and carrying on activities and interactions. We propose an environment to support the cycle of creating and dealing with...
One of the most important work group support issues is providing information about the context under which a group interacts. The goal of this paper is evaluating the influence of contextual information on the cooperation level in group interactions supported by groupware. A laboratory case study was set up and carried out with this purpose
Organizations are increasingly interested in improving their business processes. One strategy for achieving this improvement has been to model their business processes and to automate them using workflow technology. One of the difficulties in this approach is that organizations must adapt their defined processes to each different situation and that workflow systems are yet not flexible enough to allow...
Research has been done in order to propose solutions that enhance interactions among participants and improve activity coordination in the meeting cycle. Some of these are related to pre-meeting phase conduction. We argue that collaboration could be enhanced if we supplied relevant context information through awareness mechanisms. This paper aims at evaluating context elements in an asynchronous Web-based...
Knowledge management has become a prominent subject for organizations, but often characterization and treatment of information are still chaotic or even left aside. We argue that context is the fundamental information resource for better understanding and carrying out of activities and interactions. The goal of this paper is to propose the architecture of an environment supporting the cycle of organizing...
