Requirements elicitation techniques as communication channels: A framework to widen the window of understanding.

This chapter highlights the criticality of communication in requirements elicitation. Using the concept of channel expansion, a broad reclassification of requirements elicitation techniques according to their communication emphasis is presented. This classification is used to develop a model that can be used to diagnose the communication needs in a specific project setting and to provide guidance in the selection of requirements elicitation techniques best suited to that setting. The chapter offers suggestions for the practical application of the theoretic frameworks and identifies fruitful avenues for future research
