scope:

This is a recommended practice for writing software requirements speciÞcations. It describes the content and qualities of a good software requirements speciÞcation (SRS) and presents several sample SRS outlines.

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. However, application to already-developed software could be counterproductive.

When software is embedded in some larger system, such as medical equipment, then issues beyond those identiÞed in this recommended practice may have to be addressed.

This recommended practice describes the process of creating a product and the content of the product. The product is an SRS. This recommended practice can be used to create such an SRS directly or can be used as a model for a more speciÞc standard.

This recommended practice does not identify any speciÞc method, nomenclature, or tool for preparing an SRS.
