From the IEEE standard, the SRS should address the following:
● Functionality. What is the software supposed to do?
● External interfaces. How does the software interact with people, the system ’ s hard-
ware, other hardware, and other software?
● Performance. What is the speed, availability, response time, recovery time of vari-
ous software functions, etc.?
● Attributes. What are the portability, correctness, maintainability, security, etc.
considerations?
● Design constraints imposed on an implementation. Are there any required stand-
ards in effect, implementation language, policies for database integrity, resource
limits, operating environment(s) etc.?^1
In short, the SRS should not include any design requirements. The benefits of a good SRS:
● Establish the basis for agreement between the product team and the development
team.
● Reduce the development effort.
● Provide a basis for estimating costs and schedules.
● Provide a baseline for validation and verification.
