Survey on Requirement Elicitation Techniques: It's Effect on Software Engineering

Abstract

Requirement Elicitation is one of the important factors in developing any new application. Most of systems fail just because of wrong elicitation practice. A requirement may be defined as a demand or need. In software engineering, a requirement is a description of what a system should do. System may have dozen to thousands of requirements. Without the elicitation techniques it is impossible to find out requirements and the needs of the developing system. It provides base for the developer to construct a structure of proposed system keeping in view the wish list of stake holders. This paper is based on understanding elicitation techniques and their usage in real time applications, by implementing the Elicitation techniques for knowing the needs of stakeholder so that system developer can get clear view of requirement for the developing system. Furthermore this paper provide the flexibility to requirements engineers to know the characteristics and effectiveness of every techniques, it will serve as a guideline in selecting a particular elicitation technique in respect to the type of application and situation.
