An Empirical Investigation on Text-Based Communication in Distributed Requirements Engineering

Among the software development activities, requirements engineering is one of the most communication-intensive and then, its effectiveness is greatly constrained by the geographical distance between stakeholders. For this reason, the need to identify the appropriate task/technology fits to support teams of geographically dispersed stakeholders plays a key role for coping with the lack of physical proximity when developing requirements. In this paper we report on an empirical study that assessed the use of synchronous text-based communication in distributed requirements workshops, as compared to face-to-face (F2F), and the effects of computer-mediated communication (CMC), with respects to the different tasks of distributed requirements elicitation and negotiation. First results show that, in terms of satisfaction with performance, CMC elicitation is a better task/technology fit than CMC negotiation. Furthermore, the general preference for F2F over CMC is due to the strong preference for the F2F negotiation fit over the CMC counterpart.
