Abstract: Requirements engineering is one of the most communication-intensive activities in software development, greatly affected by project stakeholder geographical distribution. Despite advances in collaboration technologies, global software teams continue to experience significant challenges in the elicitation and negotiation of requirements. Deciding which communication technologies to deploy to achieve effective communication in distributed requirements engineering activities is not a trivial task. Is face-to-face or text-based communication more appropriate for requirements elicitations and negotiations? In teams that do not have access to face-to-face communication, is text-based communication more useful in requirements elicitations than in requirements negotiations? Here, we report an empirical study that analyzes the effectiveness of synchronous computer-mediated communication in requirements elicitations and negotiations. Our investigation is guided by a theoretical framework that we developed from theories of computer-mediated communication, common ground, and media selection for group tasks; a framework that considers the effectiveness of a communication medium in relation to the information richness needs of requirements elicitation and negotiation tasks. Our findings bring forward empirical evidence about the perceived as well as objective fit between synchronous communication technology and requirements tasks. First, face-to-face is not always the most preferred medium for requirements tasks, and we reveal a number of conditions in which, in contrast to common belief, text-based communication is preferred for requirements communication. Second, we find that in evaluating outcomes of requirements elicitations and negotiations objectively, group performance is not affected by the communication medium. Third, when groups interact only via text-based communication, common ground in requirements negotiations takes longer to achieve than in requirements elicitations, indicating that distributed requirements elicitation is the task where computer-mediated communication tools have most opportunity for successful application.
