BRS vs SRS: Know the Difference Between SRS and BRS

System requirement specification SRS and business requirement specification BRS are often confused with each other. In fact, there is a significant difference between SRS and BRS

Difference between a Specification and Requirement 

Before understanding SRS and BRS we should know the difference between Specification and Requirement. A specification is written to define how something should or will be made. It can also be used to define what you should be doing. The specification can be read by anyone to know what they should do or how it should be done, but you will also need to communicate with your team members who build this product. This means that they should include some other information in there as well so they know how to interpret the words on the page. Those first for should for example be written in first-person perspective because they are personal instructions for someone specific.

Here are some of the differences:

  • A Requirement is something that has to be met for a program to work at all.
  •  A Specification is something that has to be met if the program is going to be usable in a particular way.
  • A Specification can describe things that don’t need to be implemented (or even understood) by the programmer writing the program.
  •  A Requirement must describe things that do need to be implemented (and understood) by the programmer writing the program.
  • A Specification can describe things that may or may not be implemented, and may or may not function correctly when they are (if they ever are).
  •  A Requirement must describe things that must work and cannot.
