A project requires a variety of business requirements to define clear goals and establish a scope for the work that will be undertaken. Requirements also provide context and objective ways to measure progress and success. Once business requirements are established, functional requirements are defined and developed in order to move a project forward. People commonly confuse between Business Requirement document and Functional Requirement document so here I am providing difference between both of them:
Difference Between Business Requirement Document and Functional Requirement Document
Business Requirement document (BRD) explains the “What” aspect of the Requirements i.e what is required? Business Requirement document states about the high level business requirement along with the business need and business problem
Functional Requirement document (FRD) explains the “How”aspect of the Requirements i.e “How” the “What” can be achieved. Functional Requirement document states about the functionality required in the application designed for the business problem and need mentioned in the Business requirement document. It mentions the Functional as well as Non functional requirements. Functional requirement are described with the help of Use case description and Use case diagram where as Non functional requirements like capacity, performance etc. are also mentioned.
In the next article we will talk about UML and Use cases, till then happy reading!!
