Tag: Difference between BRD and FRD

Difference between BRD and FRD in software development (based on work by Frans Lüscher) The Brd format allows for much better definition of functions than the FRDs. Some programs might only need a few parameters, while others require 100+ variables with very complicated names. To help maintain this difference when performing code review, we call our algorithm “brained support” so that it is easy to understand! In contrast: In Software Development you can’t just use an array variable; there have been many examples such as if($vars={} ) where $array[$i] doesn’ t actually equal 1. We will explain how these mistakes could be prevented or avoide

Difference between BRD and FRD in software development. : An essential distinction between BRF and FRV. It is best to divide the code into three categories – Main, Sub-Sections or Tools (also known as APIs). Within a certain range of functionality any function can be divided depending on whether it applies to one part,or all parts. If not you will have different kinds which often depend significantly on each other : When working with libraries there are many ways for multiple tasks to apply differently so if an API exists then its scope expands while functions that use them would need to expand too! As such they may overlap but once combined your project might differ from original source files thus renderin

BRD vs FRD – Difference with Examples

Many business analyst beginners confuse BRD and FRD. If you are preparing for a business analyst interviews, you must know the difference between BRD and FRD. One document explains what the business needs and the other explains how the system will work.

Many beginners in business analysis get confused between two important documents that is BRD and FRD. Some people even think they are the same document but in real products they serve very different purposes. If you want to become a business analyst or prepare for interviews, you must clearly understand BRD versus FRD.

Real-Time Example (Food Delivery App)

Imagine a company wants to build a food delivery mobile app. Customer should be able to browse restaurants, place orders, make payments. Here you can imagine Zomato app or Swiggy app.

Before development starts, business analysts prepare two important documents. The first document is BRD and the second document is FRD. But these documents explain different levels of details.

What is BRD?

What is business requirement document? BRD explains business goals, project objectives, high-level requirements.

Example BRD requirement:
The system should allow customers to order food online.

Notice something important here. BRD explains what the business needs. That means what client is expecting or what customer is expecting from the IT company.

What is FRD?

What is FRD? Functional requirement document. FRD explains system functionality, detailed workflows, technical behavior.

Example FRD:
User selects a restaurant, adds food items, proceeds to checkout, payment is processed, order confirmation is generated.

FRD explains how the system will work.

Simple Trick to Remember

Here is a simple trick to remember what is BRD and what is FRD.

What does the business need?
BRD answers what does the business need or what does the business requirement.

FRD answers how will the system implement it.

This is the core difference between BRD and FRD.

BRD focus business perspective, audience stakeholders and managers content high-level requirement.

FRD focus system functionality, audience developers and testers content detailed technical requirements.

Another Real-Time Example

Let us compare one requirement

BRD requirement:
The system should allow users to transfer money.

FRD requirement:
User enters account number system validates account user enters amount system checks the balance then transaction completed.

Now you can clearly see the difference between BRD and FRD.

When are BRD and FRD Created?

Then have these these documents created.

BRD is created first. It defines the business need. Sometimes even client will prepare the BRD and they will share with us.

Based on that BRD our BS will prepare the functional specification document or FRD.

FRD is created after the BRD. It explains how developers will build the system.

Business Requirement Document

  • BRD highlights “Business Requirements” – i.e., high-level business goals of the organization developing the product or solution with the help of IT.
  • A formal document illustrating the requirement provided by the client
  • In other words it describes at very high level the functional specifications of the software
  • The requirements could be collected either by verbal or written or both
  • Created by a Business Analyst who interacts with the client
  • Entire work is executed under the supervision of the Project Manager
  • It is derived from the client interaction and requirements

The BRD is important since it is the foundation for all subsequent project deliverable, describing what inputs and outputs are associated with each process function. It describes what the system would look like from a business perspective. Following are the most common objectives of BRD –

  • To arrive at a consensus with stakeholders
  • To provide input into the next phase of the project
  • To explain how customer/business needs will be met with the solution
  • Holistic approach to business needs with the help of strategy that will provide some value to the customer

Basically, stakeholder’s requirements can be small or big. Thus it needs to be break wherever it requires and should be taken as multiple requirements.

Format Of BRD –

There are many formats or templates that the organization follows. However, it depends upon the practices that is carried in the organization. For a product based company the BRD format is different as compared to service based firms. Standard format which is followed in most organizations are shown below. It is important to note that for clear understanding of the document we should include list of acronyms used.

The BRD template contains –

  • document revision
  • approvals
  • introduction
  • business goals
  • business objectives
  • business rules
  • background
  • project objective
  • project scope
  • in-scope functionality
  • out-scope functionality
  • assumptions
  • constraints
  • risks
  • business process overview (modelling diagrams for instance, Use Case and Activity Diagram)
  • legacy systems
  • proposed recommendations
  • business requirements
  • list of acronyms
  • glossary of terms
  • related documents

Now let us look into FRD…

Functional Requirement Document

  • FRD highlights “Functional Requirements” i.e., functionality of the software in detail
  • Depending on the product.
  • It will describes at a high level the functional and technical specification of the software
  • Usually created by Business Analyst under the supervision of technical expert, for instance System Architect
  • In a small and medium sized organizations a BA take care of this
  • Few companies did not create FRD, instead they used BRD as it is detailed enough to be used as FRD as well
  • FRD is derived from the BRD
  • Will get sign off from the client once we prepare FRD

Actually, the process to reach the expectancy of the BRD is an FRD itself. Business Analyst will prepare the FRD after discussing with the stake holders and Project Manager. He is the person analyze the requirements, to get clarity on requirements he will conduct multiple meeting session with internal and external stake holders. And he will concentrate on below questions mostly.

  • How we develop the expected requirement(s)?
  • What are the tools and/or systems used and their dependencies?
  • What are the features and functionalities?
  • How will the customer reacts when they start using the solution?
  • Any assumptions or constraints?

Most common objectives of FRD –

  • Draw flow charts for each process flows for each activity interlinking dependencies
  • Holistic view for each and every requirements, steps to built
  • Estimating detailed risks for each new change request
  • Highlight the consequences if the project health is weak to avoid scope creep

The FRD should document the operations and activities that a system must be able to perform.

Format Of FRD –

Likewise BRD, FRD has a somewhat different format focusing more on risks and interfaces. Although there is no such standard format that a Business Analyst should opt for. Companies belonging to different domains use their own template. For instance, you would find many points would be repeating as in BRD.

But there should be no confusion for BA to prepare this document.

The FRD template contains –

  • Introduction – It should contain Purpose, Scope, Background, References, Assumptions and constraints, document overview
  • Methodology
  • Functional Requirements
  • Modeling Illustrations – Context, User Requirements, Data Flow Diagrams, Logical Data Model/Data Dictionary, Functional Requirements
  • Other Requirements – Interface Requirements, Hardware/Software Requirements,
  • Glossary

Now the use of BRD or FRD in organizations depends on the organization policies, practices followed by the project team and stakeholders. In my company client will share the BRD, based on the BRD we prepare FSD.

I hope now you understand the BRD vs FRD
