Software Requirement Specification (SRS) is a document that explains what the software is suppose to do and how it is expecting to work. It also describes the functionality needed by the product to fulfil the needs of all stakeholders (business, users).
A standard SRS consists of –
A purpose – Initially, the main objective is to clarify and illustrate why this document is important and what the intention of the document is.
An overall description – The product summary is explained here. It’s simply a rundown or an overall product analysis.
Scope of this document – This outlines and demonstrates the overall work and primary goal of the paper and what value it can bring to the consumer. It also provides a summary of the cost of construction and the necessary time.
When embedded in hardware, or when linked to other software, the best SRS documents describe how the software can communicate.
Why do we use the Software Requirement Specification document?
For your entire project, a software specification is a foundation. It sets the structure that will be following any team involved in development.
It is used to provide multiple teams with essential information – creation, quality assurance, operations, and maintenance. This keeps it on the same page for everybody.
The use of the SRS helps ensure the fulfilment of specifications. And it can also help you make decisions about the lifecycle of your product, such as when to remove a feature.
Writing an SRS can also reduce time and costs for overall production. The use of an SRS especially benefits embedded development teams.
The process to gather the software requirements from clients, analyse and document them is known as requirement engineering main goal of requirement engineering is to develop and maintain a sophisticated and descriptive ‘System Requirements Specification’ documents.
Steps
Requirement Engineering Process includes four steps:
a) Feasibility Study
b) Software Requirement Specification
c) Requirement Gathering
d) Software Requirement Validation
