SRS (software requirement specification) is a key document which explains all details with respect to the project development, in its initial stage of SDLC. It contains all the validated Functional and Non-functional requirements, listed priority wise.
It is created by the business analyst and contains all information indicating his understanding about the business need and thus suggesting solution accordingly. Function requirements are gathered and analyzed by BA and well documented in BRD (Business Requirement document) and All Architect list technical requirements and document it in SSD (Supplementary support documents).
Together BRD and SSD are documented in SRS, which thus is the first legal binding document between the Business owner and Project stakeholder.
