Why writing a Business Requirement Document (BRD) is important and how it helps in application success?

Business requirement document for software, mobile app, website

If you are planning of building an application either Website or mobile app, having a clear requirements is the key to success.Whether you are a startup with an original idea, or a company, it is essential that each and every project starts with a BRD.

A clear BRD makes the development process much smoother which will act as a foundation of the product, outlining the business logic, listing the technical specifications, and finally to ensure your application reaches its full potential once it is live.

The two important Variants of BRD are

  1. Requirement Specification document (RDS)
  2. Functional Specification Document (FSD)

Both sets of requirements contribute to a common Project. Requirement specification document deal with mainly business goals and stakeholder expectations whereas functional requirements are very detailed and provide information on how business needs and goals will be delivered through a specific project.

Requirement specification document contain following elements:

  • Vision of the project
  • Objectives of the project
  • Context or background of the project
  • Scope of the project
  • Stakeholder identification
  • Detailed Business Requirements
  • Scope of the solution
  • Project constraints: Time Frame, Cost of the Project, and Available resources

Functional Specification document contains following details:

  • Purpose of the project
  • Scope of the project
  • Detailed functional requirements
  • Non-functional requirements
  • Assumptions/constraints
  • Representation of functional requirements using Information Architecture

A Simple example that explains the difference between Requirement specification and Functional Specification is

Subject: Development of a classified’s Website

Business Requirements

“Build a responsive online classifieds listing website where users can search and browse classifieds by Categories, City and State and can also view and rate other user’s profiles, and post classifieds for free as well as Job classifieds.”

Functional Requirements

The system shall allow the user to post a classified by providing title, price, location, description, state/area, uploading a picture, and selecting a category.

The system shall allow the rating of users on a scale of 1-5.

The system shall allow the users to Search Classifieds by Keyword, Category, State, City and Church.
