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.
There are different types of specifications, which generally are mostly types of documents, forms or orders or relates to information in databases. The word Specification merely refers to the act of To state explicitly or in detail or to be Specific. A specification may refer to a type of technical standard (the main topic of this page). Using the word specification without additional information to what kind of specification you refer to is confusing and considered bad practice within systems engineering. A Requirement specification is a set of documented requirements to be satisfied by a material, design, product, or service.
