Distinction among BRS, FRS, and SRS – Top 7
The difference among SRS, FRS, and BRS seems to be same but in reality, they all are different and important too because many of us do not know these simple basic terms, in simply we know these terms but not exactly.
| SRS | FRS | BRS |
| 1. It means “Software Requirement Specification” (SRS). | 1. It means “Functional Requirement Specification” (FRS). | 1. It means “Business Requirement Specification” (BRS). |
| 2. It deals with resources provided by Company. | 2. It deals with requirements given by the client. | 2. It deals with aspects of business requirements. |
| 3. It always includes Use cases to describe the interaction of the system. | 3. In this, Use cases are not included. | 3. In this, Use cases are also not included. |
| 4. It is developed by System Analyst. And it is also known as User Requirement Specifications. | 4. It is always developed by developers and engineers. | 4. It is always developed by Business Analyst. |
| 5. In SRS, we describe all the business functionalities of the application. | 5. In FRS, we describe the particular functionalities of every single page in detail from start to end. | 5.In BRS, we define what exactly customer wants. This is the document which is followed by the team from start to end. |
| 6. SRS tells means explains all the functional and non-functional requirements. | 6. FRS tells means explains the sequence of operations to be followed on every single process. | 6. BRS tells means explains the story of whole requirements. |
| 7. SRS is a complete document which describes the behavior of the system which would be developed. | 7. FRS is a document, which describes the Functional requirements i.e. all the functionalities of the system would be easy and efficient for the end user. | 7. BRS is a simple document, which describes the business requirements on a quite broad level. |
