The Software Requirements Specification (SRS) specifies the requirements to be satisfied by a
software item (eg software system, subsystem, CSCI, component or other item) and the methods to be
used to ensure that each requirement of the software item has been so satisfied. Requirements
pertaining to the software item’s external interfaces may be presented in the SRS or in one or more
Interface Requirements Specifications (IRSs) referenced from the SRS.
The SRS, possibly supplemented by IRSs, is used as the basis for procurement, design, qualification
testing and acceptance testing of the software item. Throughout this DID, the term "software item"
may be interpreted to mean "CSCI", "software system", "software subsystem", "software component"
or other item, as applicable.
This Data Item Description (DID) may be cited in a Statement of Requirement (SOR), Statement of
Work (SOW), a Contract Data Requirements List (CDRL), within a standard invoked by a SOR or
SOW, or within a plan or procedure.
This DID incorporates and adapts some non-copyrighted material contained in Software Requirements
Specification (SRS) DID DI-IPSC-81433 issued by the United States Government.
