Enhancement approach for non-functional requirements analysis in Agile environment

Non-functional requirements (NFRs) are quality attributes that define how a software product will do its functions. They are important and critical to the success of any software in the market as they considered as the differentiating factor from other software products that provide similar functionality. Agile methodology became popular during the last few years, and although it improves the process of software development, it has a number of limitations regarding requirements analysis. Neglecting the non-functional requirements is one of the biggest limitations in Agile. It doesn´t provide any widely accepted technique for elicitation and management of non-functional requirements. This paper summarizes two existing approaches that are currently used to analysis NFRs, and then it provides an enhanced approach for better analysis of NFRs. The new approach is better than the existing ones, because it combines their strengths and overcome their weaknesses.
