A Software Requirements Specification (SRS) is a formal document that describes the functional and non-functional requirements of a software system. It defines what the software should do, the constraints under which it must operate, and the services it should provide to users. An effective SRS acts as a communication bridge between customers, users, developers, testers, and project managers. A well-prepared SRS reduces ambiguity, prevents misunderstandings, and provides a foundation for software design, development, testing, and maintenance. One important characteristic of a good SRS is correctness. The requirements stated in the document must accurately represent the actual needs of the customer and users. Every requirement should describe a feature or constraint that is genuinely required by the system. Incorrect or unnecessary requirements can lead to wasted development effort and increased project costs. Requirements should therefore be verified with stakeholders before being included in the SRS. The second characteristic is unambiguity. Each requirement should have only one possible interpretation. Ambiguous statements can cause developers and customers to understand the same requirement differently. For example, a statement such as “the system should respond quickly”
