A System Requirements Specification (SRS) or a Software Requirements Specification is a document or set of documents that describe the features of a system or software application. It includes a variety of elements which define the intended functionality required by the stakeholders and customer to satisfy the end users.
In addition to that, an SRS provides a high-level idea of the system and its behavior, the main supported business processes, the assumptions and the key performance parameters for the system. The key elements of an SRS are:
? Scope of Work
? Functional Requirements
? Non-Functional Requirements
? Dependencies
? Data Model
? Assumptions
? Constraints
