System requirement specification vs functional one - separate docs?
- by user970696
A lot of sources (e.g. Wikipedia) mentiones System requirement specification and Functional specification as two separate entities.
However, Wiegers in his book writes:
The software requirements specification is sometimes called a
functional specification, a product specification...
This is very confusing for me as I thought FS describes just functions while SRS whole system. From this point of view, FS would contain both non functional and functional requirements and everything else.
