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, if required,
corresponding verification requirements. 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, verification
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), Task
Specification (TS), a Contract Data Requirements List (CDRL), within a standard invoked by a SOR
or SOW, or within a plan or procedure.
