Understanding the Use of Elicitation Approaches for Effective Requirements Gathering

Requirements sometimes can turn out to be either incomplete or inconsistent. Factors contributing to this situation include the selection of the elicitation technique and other approaches used. Some approaches used for requirements gathering such as single elicitation approach, and their effects during requirements elicitation, can cause deficiency in many requirements elicitation methods. Our experimental study showed that when an interview technique is used, choice-based and integration-based approaches are far better than a single elicitation approach, as they provide an effective process for eliciting complete and correct requirements.
