WNR approach: An extension to requirements engineering lifecycle

Requirements engineering (RE) plays a vital role in ensuring the overall success of the software engineering process. Requirements elicitation, which describes the expected behavior of the desired software, is very complicated. In this paper, a new approach, named WNR, is proposed which put emphasis on discovering the user wishes and transforming them to a set of needs and subsequently obtaining the set of desired requirements out of the needs. The new proposed approach is an extension to RE lifecycle. Moreover, the definitions of the terms “requirement” and “requirements engineering” are reviewed in this paper. The new definition of RE in the proposed approach is also elaborated.
