SOFTWARE REQUIREMENT DOCUMENT

* It is also called as Software Requirement Specification [SRS]
* This requirement document includes;
=> Requirement definition
=> Requirement Specification
* The software requirement document is not a design document
* It should set out
=> what the system should do without specifying, how it should be done
* If services, constraints and properties specified in the document are satisfied by
software design than,
=> the design is an acceptable solution to the problem

* There are Six requirements which a software requirements document should satisfy:
(i) It should only specify external system behavior
(ii) It should specify constraints on the implementation
(iii) It should be easy to change
(iv) It should serve as a reference tool, for system maintainers
(v) It should record forethought about the life cycle of the system
(vi) It should characterize acceptable responses to undesired events
