Constraints, assumptions and dependencies.Īn example organization of an SRS is as follows: Typically a SRS is written by a technical writer, a systems architect, or a software programmer. The SRS may be one of a contract's deliverable data item descriptions or have other forms of organizationally-mandated content.

This is achieved through detailed and continuous communications with the project team and customer throughout the software development process. To derive the requirements, the developer needs to have clear and thorough understanding of the products under development. The software requirements specification document lists sufficient and necessary requirements for the project development. Used appropriately, software requirements specifications can help prevent software project failure. It should also provide a realistic basis for estimating product costs, risks, and schedules. Software requirements specification is a rigorous assessment of requirements before the more specific system design stages, and its goal is to reduce later redesign. Software requirements specification establishes the basis for an agreement between customers and contractors or suppliers on how the software product should function (in a market-driven project, these roles may be played by the marketing and development divisions). The software requirements specification lays out functional and non-functional requirements, and it may include a set of use cases that describe user interactions that the software must provide to the user for perfect interaction. It is modeled after business requirements specification ( CONOPS), also known as a stakeholder requirements specification (StRS).

A software requirements specification ( SRS) is a description of a software system to be developed.
