Explain SRS and its key elements

Before staring any project, or to understand the problems of the clients, solutions and scope for the project. The Business Analyst do the Requirement gathering.

SRS which stands for Software Requirement Specification, it’s a document prepared by Business Analyst with the help of Technical Team. It describes what will be the software features.

SRS the Software Requirement Specifications as name suggests is a complete descriptions of the requirement of the software that need to be fulfilled for successful development of software application or product. These requirements can be functional and non-functional. It is depending upon the type of requirements needed for the software development.

After successfully gathered the requirements, SRS is prepared and which describes the features of the software that includes changes or modifications that is needed to be done to improve the quality of the software and satisfy the clients.

SRS document is required for the development of the product as per the requirements.

Key elements of SRS are

1. Introduction:
2. Purpose of the Document:- While preparing SRS document, it is necessary to understand why this document is necessary and also the main purpose of the SRS document is described.
3. Scope of the Document:- While preparing SRS document, it explains the main objective of the document that what kind of value will provide to its customer.
