What is a System Requirements Specification (SRS)? A System Requirements Specification (SRS) (also known as a Software Requirements Specification) is a document or set of documentation that describes the features and behavior of a system or software application.
Requirements include descriptions of system properties, specifications for how the system should. work, and constraints placed upon the development process. Generally, requirements are. statements of what a system should do rather than how it should do it. The answers to how. questions fall into the realm of design. Requirements specifications should not include design. solutions (except for interface requirements, which often include embedded design).
