Effectiveness of Elicitation Techniques in Distributed Requirements Engineering

Software development teams are often geographically distributed from their customers and end users. This creates significant communication and coordination challenges that impact the effectiveness of requirements engineering. Travel costs, and the local availability of quality technical staff increase the demand for effective distributed software development teams. This research reports an empirical study of how groupware can be used to aid distributed requirements engineering for a software development project. Six groups of seven to nine members were formed and divided into separate remote groups of customers and engineers. The engineers conducted a requirements analysis and produced a software requirements specification (SRS) document through distributed interaction with the remote customers. We present results and conclusions from the research including: an analysis of factors that effected the quality of the Software Requirements Specification document written at the conclusion of the requirements process and the effectiveness of requirements elicitation techniques which were used in a distributed setting for requirements gathering

Negotiation of software requirements in an asynchronous collaborative environment

The effect of task structure and negotiation sequence on collaborative software requirements negotiation is investigated. This work began with an extensive literature review that focused on current research in collaborative software engineering and, in particular, on the negotiation of software requirements and the requisite collaboration for the development of such requirements. A formal detailed experiment was then conducted to evaluate the effects of negotiation sequence and task structure in an asynchronous group meeting environment. The experiment tested the impact of these structures on groups negotiating the requirements for an emergency response information system. The results reported here show that these structures can have a positive impact on solution quality but a negative impact on process satisfaction, although following a negotiation sequence and task structure can help asynchronous groups come to agreement faster. Details of the experimental procedures, statistical analysis, and discussion of the results of the experiment are also presented, as are suggestions for improving this work and a plan for future research
