Achieving agreement with respect to software requirements is a collaborative process that traditionally relies on same-time, same-place interactions. As the trend toward geographically distributed software development continues, colocated meetings are becoming increasingly problematic. Our research investigates the impact of computer-mediated communication on the performance of distributed client/developer teams involved in the collaborative development of a requirements specification. Drawing on media-selection theories, we posit that a combination of lean and rich media is needed for an effective process of requirements negotiations when stakeholders are geographically dispersed. In this paper, we present an empirical study that investigates the performance of six educational global project teams involved in a negotiation process using both asynchronous text-based and synchronous videoconferencing-based communication modes. The findings indicate that requirement negotiations were more effective when the groups conducted asynchronous structured discussions of requirement issues prior to the synchronous negotiation meeting. Asynchronous discussions were useful in resolving issues related to uncertainty in requirements, thus allowing synchronous negotiations to focus more on removing ambiguities in the requirements.

Traditionally, software inspection has largely relied on collocated interaction of inspectors. As companies have begun to turn to distributed software development, meeting in a room has become impractical. In this paper we report on controlled experiment to assess the effect of synchronous and asynchronous communication in remote inspection meetings.

Important and yet very difficult process in software development, requirements engineering is plagued with additional challenges in the emergent dynamics of geographically distributed software teams. Our hypothesis is that a mix of lean and rich communication media are needed towards increasing the effectiveness of meetings in reaching mutual agreement when stakeholders are geographically dispersed.We studied tool-supported remote inspections in six educational global project teams in a multicultural software development environment. In this paper we present the preliminary results from comparing the effectiveness of the requirements negotiations when preceded by the asynchronous discussions to those negotiations with no prior asynchronous discussions.

Software inspection is one of the best practices for detecting and removing defects early in the software development process. We present a tool to support geographically distributed inspection teams. The tool adopts a reengineered inspection process to minimize synchronous activities and coordination problems, and a lightweight architecture to maximize easy of use and deployment.
