The software project success largely depends of a proper process of software requirements elicitation, also the quality of these requeriments improves as the participation of stakeholders grows. This participation becames difficult when software requirements elicitation is performed in a distributed environment. Therefore, the elicitation process in distributed environments requires a platform that promotes the effective and efficient collaboration of those involved. Wikis can be useful tools for this purpose. This paper presents a controlled experiment performed to evaluate usage of wiki as party of a collaborative strategy of distributed requirement elicitation. The study addressed a real problem with the participation of undergraduate students and shows that using a wiki tool a Software Requirements Documents more precise is obtained.
