Use of reference model for formal specification of NFR
Harsimran Kaur, Ashish Sharma · 2016
Requirement Engineering plays a very significant role in order to encode domain knowledge (customers) and implementation strategies (developers). Further, for the development of quality software, it is indeed necessary to specify both functional and non-functional requirement for the proposed software especially for those who program it. Hence, it is must to model the non-functional properties of the system. However, focus of modeling requirements is limited to the functional requirements only. Hence, this paper addresses the issue of specifying Non Functional Requirements (NFR) by integrating the NFR with Reference Model on the basis of soft nature of NFRs. Result analysis validates the claim that the proposal presented in this paper is compared well with various established measures. For validation purpose the sensitivity analysis is also carried out.
