6、nIEEE Standardsdocuments are developed within the IEEE Societies and the Standards Coordinat-ing Committees of the IEEE Standards Association (IEEE-SA) Standards Board. Members of thecommittees serve voluntarily and without compensation. They are not necessarily members of theInstitute. The standard
7、s developed within IEEE represent a consensus of the broad expertise on thesubject within the Institute as well as those activities outside of IEEE that have expressed an inter-est in participating in the development of the standard.Use of an IEEE Standard is wholly voluntary. The existence of an IE
8、EE Standard does not implythat there are no other ways to produce, test, measure, purchase, market, or provide other goods andservices related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at thetime a standard is approved and issued is subject to change brought about throu
9、gh developments inthe state of the art and comments received from users of the standard. Every IEEE Standard is sub-jected to review at least every five years for revision or reaffirmation. When a document is morethan five years old and has not been reaffirmed, it is reasonable to conclude that its
10、contents,although still of some value, do not wholly reflect the present state of the art. Users are cautioned tocheck to determine that they have the latest edition of any IEEE Standard.Comments for revision of IEEE Standards are welcome from any interested party, regardless ofmembership affiliatio
11、n with IEEE. Suggestions for changes in documents should be in the form of aproposed change of text, together with appropriate supporting comments.Interpretations: Occasionally questions may arise regarding the meaning of portions of standards asthey relate to specific applications. When the need fo
12、r interpretations is brought to the attention ofIEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards rep-resent a consensus of all concerned interests, it is important to ensure that any interpretation hasalso received the concurrence of a balance of intere
13、sts. For this reason, IEEE and the members of itssocieties and Standards Coordinating Committees are not able to provide an instant response tointerpretation requests except in those cases where the matter has previously received formalconsideration.

This guide serves theanalyst by providing a clear definition f
19、or identifying well-formed requirements and ways of organizingthem.This guide should be used to help the analyst capture requirements at the beginning of the system require-ments phase. It should be used to clarify what constitutes a good requirement and provide an understandingof where to look to i

Overview1.1 ScopeThis guide provides guidance for the development of a set of requirements that, when realized, will satisfyan expre
40、ssed need. In this guide that set of requirements will be called the System Requirements Specica-tion (SyRS). Developing an SyRS includes the identication, organization, presentation, and modication ofthe requirements. This guide addresses conditions for incorporating operational concepts, design co
41、nstraints,and design conguration requirements into the specication. This guide also addresses the necessary charac-teristics and qualities of individual requirements and the set of all requirements.This guide does not specify industry-wide system specication standards nor state a mandatory SystemReq
42、uirements Specication. This guide is written under the premise that the current state of the art of systemdevelopment does not warrant or support a formal standards document.2.
