This guide provides guidance for the development of a set of requirements that, when realized, will satisfy an expressed need. In this guide that set of requirements will be called the System Requirements Specification (SyRS). Developing an SyRS includes the identification, organization, presentation, and modification of the requirements. This guide addresses conditions for incorporating operational concepts, design constraints, and design configuration requirements into the specification. This guide also addresses the necessary characteristics and qualities of individual requirements and the set of all requirements. This guide does not specify industry-wide system specification standards nor state a mandatory System Requirements Specification. This guide is written under the premise that the current state of the art of system development does not warrant or support a formal standards document.
