Software testing is the process of examining and verifying the correctness of software by considering its all attributes like Reliability, Scalability, Portability, etc, and evaluating the execution of the software components to find the software bugs or errors, or defects. This article focuses on discussing the difference between Business requirements specification and Software requirement specification.

What is BRS (Business Requirement Specification)?

A business requirement specification, or BRS, is a document that outlines how to achieve business requirements on a larger scale. One of the most generally accepted specification documents is a BRS document. It’s critical, and a BRS is typically produced at the start of a product’s life cycle to outline the key product goals or needs that the client wishes to meet with specific software or products. A business analyst usually creates this one based on the specifications of other stakeholders and after a comprehensive examination of the client organization. The customer usually reviews the final version of the document to ensure that all business stakeholders’ expectations are met. 

Features of BRS:

  1. It is a list of all the requirements that a client has requested. 
  2. It includes the product’s goal, users, the general scope of work, all mentioned features and functions, as well as usability and performance criteria. 
  3. Use cases, as well as diagrams and tables, are not included in this type of paper. 
  4. Upper and middle management, product investors, and business analysts are the primary users of a BRS.

BRS Covers:

  1. The project’s objective.
  2. The product’s scope features and functionalities.
  3. Requirements for usability.
  4. The product’s users.
  5. The project’s scope.
  6. Requirements for performance.

What is SRS (Software Requirement Specification)?

A software requirement specification, or SRS, is a document created by a group of system analysts that describes software that will be built, as well as the key business purpose and functionality of a product and how it accomplishes its fundamental functions. An SRS serves as the foundation for any project because it consists of a framework that each team member must adhere to. An SRS is also the foundation for a contract with stakeholders (users/clients) that includes all of the information regarding the future product’s functionality and how it should operate. During the creation of a product or program, software engineers frequently employ an SRS. 

Features of SRS:

  1. Both functional and non-functional criteria, as well as use cases, are included in an SRS. 
  2. A flawless SRS document includes how the software will interact with other software or when it is embedded in hardware, but it also considers future users and how they will interact with the software. 
  3. It also includes references to tables and diagrams to help you grasp all of the product’s specifics. 
  4. An SRS document keeps team members from all departments on the same page and ensures that all requirements are met. 
  5. This paper also aids in the reduction of software development costs and time.

SRS Covers:

  1. SRS outlines the whole system flow, including how data will enter the system and the system’s functionality.
  2. A set of use cases is included in the SRS documentation.
  3. The SRS also includes non-functional requirements in addition to using cases.

Difference Between BRS and SRS

S No. SRS(System Requirement Specifications) BRS(Business Requirement Specifications)
1. Software Requirement Specification gives a high-level description of the software’s functional and technical requirements. Business Requirement Specification gives a high-level description of the software’s functional requirements.
2. SRS document is obtained from BRS. BRS document is obtained by relating to the client’s requirements.
3. The System Analyst is the one who created it. It is also known as User Requirement Specifications. Business Analysts are always the ones who create it.
4. SRS document describes the stepwise sequence of all the operations characteristics for each module and sub-modules. The BRS document includes what the customer exactly wants. and the team follows the document from beginning to conclusion.
5. SRS covers all functional and non-functional requirements. BRS covers all types of requirements.
6. The report of user connections is prepared in SRS. BRS specifies how clients communicate with the system with the help of use cases.
7. It is a formal document that details the client’s requirements (written, verbal). Non-technical expression is used to describe the requirements of the client.
8. The BRS document covered the product’s future scope, as well as the organization’s development strategies. The scope of the product is not covered in the SRS document.
9. The BRS document may or may not contain the references of figures and tables. The SRS document always includes references to figures and tables.
10. The SRS document does not list anyone from the client side. The BRS document list the user base and similar stakeholders from the client-side.
