As software systems become more and more complex with a multitude of stakeholders involved in development activities, novel ways of conducting the process of requirements elicitation and analysis are to be found. Therefore, this paper introduces a method for collaborative requirements elicitation and decision-supported requirements analysis. Accompanying this method, appropriate tools and techniques, both existing and custom-made, are referred to. The method is designed for a geographically distributed collaborative environment in order to support software manufacturers as well as IT departments which develop software solutions for multiple users or even consortiums of customers.1st International Workshop on Advanced Software Engineering: Expanding the Frontiers of Software Technology - Session 3: Software Development ProcessRed de Universidades con Carreras en Informática (RedUNCI)
