IEEE Std 830-1993 IEEE Recommended Practice for Software Requirements Specifications -Description

Abstract: The content and qualities of a good software requirements specification (SRS) are described and several sample SRS outlines are presented. This recommended practice is aimed at specifying requirements of software to be developed but also can be applied to assist in the selection of in-house and commercial software products.

Keywords: contract, customer, prototyping, software requirements specification, supplier, system requirements specifications
