NVC Based Model for Selecting Effective Requirement Elicitation Technique

Requirement Engineering process starts from gathering of requirements i.e.; requirements elicitation.Requirements elicitation (RE) is the base building block for a software project and has very high impact on subsequent design and builds phases as well.Accurately capturing system requirements is the major factor in the failure of most of software projects.Due to the criticality and impact of this phase, it is very important to perform the requirements elicitation in no less than a perfect manner.One of the most difficult jobs for elicitor is to select appropriate technique for eliciting the requirement. Interviewing and Interacting stakeholder during Elicitation process is a communication intensive activity involves Verbal and Nonverbal communication (NVC). Elicitor should give emphasis to Non-verbal communication along with verbal communication so that requirements recorded more efficiently and effectively. In this paper we propose a model in which stakeholders are classified by observing non-verbal communication and use it as a base for elicitation technique selection.We also propose an efficient plan for requirements elicitation which intends to overcome on the constraints, faced by elicitor.
