Impact of Requirement Gathering Techniques on Software Development

Abstract

Requirement of any software project plays an important role throughout the development life cycle. It affects the system cost, effort, time estimation, system development, software   quality measures and ultimate software performance. There are many requirement gathering techniques deployed for this purpose. Some of these techniques are if good in one picture, at the same time these techniques do not provide better results in another one. In the small size software industries in underdeveloped countries, these techniques varies for the same environment. This research analyses the five common requirements gathering techniques that include interviews, questionnaires, joint application development, request for proposals and prototyping. This paper statistically analyse that the impact of these on software development.
