A Software Requirements Specification (SRS) is a document, which is used as a communication medium between the customers. A software requirement specification in its most basic form is a formal document used in communicating the software requirements between the customer and the developer.
An SRS document concentrates on WHAT needs to be done and carefully avoids the solution (how to do). It serves as a contract between development team and the customer. The requirements at this stage is written using end user terminology. If necessary, later a formal requirement specification will be developed from it.
SRS is a complete description of the behavior of a system to be developed and may include a set of use-cases that describes the interactions, the users will have with the software.
SRS is a communication tool between Customer / Client, Business Analyst, System developers, Maintenance teams. It can also be a contract between purchaser and supplier.
