This paper proposes to add both formal and informal specifications of NFR to Request for Proposal document. It ought the developers to focus on each NFR right from the beginning of development process. In this paper NFRs are specified informally by extended use case and formally by proposed extension to Formal Reference Model. The paper claims that the proposed add-ons related to NFRs are qualitative one and can be considered as standard add-ons in RFP documents to deal with NFRs. It shall act as important step during early planning system for designing and implementing proposed software. The complete procedure is illustrated using a general case of cafeteria ordering framework.
