These two acronyms represent two different types of documents that are essential when it comes to software development. While they might sound similar, there’s actually a significant difference between the two.
So, what is the difference between a BRD and an FRD? In a nutshell, a BRD is a Business Requirements Document, while an FRD is a Functional Requirements Document. The former outlines the overall goals and objectives of a project, whereas the latter focuses on the specific functionalities and features that will be developed. While both documents are crucial in ensuring project success, they serve different purposes and are aimed at different stakeholders.
As you can imagine, a thorough understanding of the difference between a BRD and an FRD is critical for any software development team or project manager. It’s not just about using the right terminology, but it’s also about ensuring that everyone is clear on what they’re working towards. In this article, we’ll take a deep dive into the specifics of these two documents, and help you understand which one you need – and when. So, let’s get started!
Understanding BRD (Business Requirement Document)
When it comes to software development and project management, a Business Requirement Document, or BRD, plays a vital role in ensuring that all stakeholders are on the same page. Simply put, a BRD is a comprehensive document that outlines the requirements, goals, and objectives of a project. This document serves as a blueprint for the team in charge of developing and implementing the project. It is also a vital tool for communicating with stakeholders and keeping them informed about the project’s progress.
- A BRD outlines the objectives and goals of a project: The BRD sets out the project’s objectives, goals, and expected outcomes. This provides a common understanding of the project’s end goals, which is critical for ensuring that everyone is on the same page before development begins.
- A BRD defines the scope of the project: The scope of a project refers to all the work needed to complete the project. The BRD outlines the scope of the project by specifying all the features, functions, deliverables, and deadlines. This helps team members stay focused on their tasks and prevents scope creep, which can lead to delays and budget overruns.
- A BRD lays out the project requirements: The BRD provides a detailed description of the project requirements, including user requirements, functional requirements, and technical requirements. This ensures that team members have clarity on what is needed to achieve the project goals.
Creating a BRD can be a time-consuming process, and the document can be lengthy and complex. However, the effort and investment in creating a well-thought-out BRD upfront can save time, money, and resources in the long run. A comprehensive BRD helps reduce misunderstandings and inconsistencies and ensures that all stakeholders have a shared understanding of the project goals and how they will be achieved.
Here’s an example of what a BRD may include:
| Section | Description |
|---|---|
| Introduction | A brief overview of the project, including its purpose, objectives, and intended audience. |
| Scope | A detailed description of the project’s scope, including timelines, deliverables, and budget. |
| Requirements | A comprehensive list of functional, technical, and user requirements, including any dependencies between various requirements. |
| Use Cases and Scenarios | A set of detailed use cases, or specific ways in which the software will be used. Scenarios outline how the software will behave under specific situations. |
| Constraints and Assumptions | A description of any technical, budgetary, or timeline constraints. This section outlines any assumptions made in the documentation. |
| Roles and Responsibilities | A clear list of project team members and their respective responsibilities. This helps ensure that all team members understand their role and responsibilities within the project. |

A well-structured BRD is an essential tool in software development and project management. It ensures that everyone involved in the project understands the objectives, goals, and requirements. By creating a comprehensive BRD upfront, project teams can mitigate risks, reduce misunderstandings, and deliver projects on time and within budget.
Understanding FRD (Functional Requirement Document)
When it comes to software and application development, a Functional Requirement Document (FRD) is an essential tool in ensuring the project’s success. Essentially, an FRD is a detailed outline of what the software or application should accomplish and what features it should possess. This document provides the developers, stakeholders, and designers with a clear understanding of the requirements of the project, and it is essential that they align with these requirements before development begins
The Difference between BRD and FRD
- Basis of creation – A business requirement document (BRD) is created from the business perspective, while an FRD is created from a functional perspective. This means that while the BRD focuses on the business’s overall goals, the FRD drills down into the functional details that will enable those goals’ achievement.
- Level of detail – Unlike the FRD, which is highly detailed and technical, the BRD is less detailed and focuses more on the big picture of the project.
- Target audience – The BRD is geared towards the management and business teams, while the FRD is created for the developers, designers, and stakeholders responsible for the project’s technical implementation.
Key Contents of an FRD
The FRD must include the following critical components.
- Introduction: This section should contain a brief summary of the proposed project, the problems it aims to solve, and the software’s expected benefits. It also outlines the project’s objectives, definitions, scope, and other high-level information.
- Functional requirements: This section outlines what the software or application should do and the features it should have to deliver the expected functionality.
- Non-functional requirements: These are the quality and performance requirements of the software that are not directly linked to the features but are expected of the software. Examples of non-functional requirements include usability, performance, reliability, and security.
- User stories: These refer to the scenarios in which users are expected to interact with the software. User stories help the developers understand the software’s intended use and develop the appropriate functionality.
- Dependencies: This section details the dependencies between various components and systems involved in the project. Understanding this information is crucial in determining the feasibility and impact of a change to the project scope or requirements.
The Benefits of an FRD
The FRD serves several critical functions, including:
| Benefit | Description |
|---|---|
| Defining project scope | The FRD defines the project’s scope, which helps to ensure everyone’s expectations align at the outset, minimizing the risk of misunderstandings later on. |
| Providing a roadmap | The FRD provides a roadmap for the project, allowing developers to identify potential obstacles and develop appropriate solutions before development begins. |
| Ensuring traceability | The FRD facilitates product traceability, allowing stakeholders to track features and functionalities throughout the development process. |
| Facilitating collaboration | The FRD brings together all stakeholders, ensuring everyone has the same information and helping to facilitate communication and collaboration between development teams and business stakeholders. |
In conclusion, a Functional Requirement Document is crucial in software and application development. When created correctly, it serves as a foundation for the project by providing clear guidance to developers and stakeholders on what features and functionalities the software should possess and what is expected of it.
BRD vs FRD: Which one to use?
When it comes to software development, two important documents are a Business Requirements Document (BRD) and a Functional Requirements Document (FRD). While both documents serve the purpose of outlining project requirements, they differ in their scope and focus. Here, we explore the differences between BRD and FRD to help you choose which document to use for your project.
BRD vs FRD: What’s the Difference?
- The BRD documents the business requirements that drive a technology project, such as the objectives, goals, and scope of the project. It provides a high-level view of the project and does not address the technical aspects of implementation.
- The FRD, on the other hand, outlines how the software will meet the business requirements specified in the BRD. It focuses on the functional aspects of the software, including system features, user interface, and data requirements.
- In essence, the BRD is a roadmap that defines the goals and objectives of a project, while the FRD describes how to achieve those goals.
BRD vs FRD: Which One to Use?
Choosing between BRD and FRD depends on the goals of your software development project. If you need to define the business requirements and scope of the project, use a BRD. This document is vital in ensuring all stakeholders are aligned with the objectives and goals of the project before development begins. It provides context and direction to the project, reducing the risk of confusion and misunderstanding as the project progresses.
If the project has already started and you need to specify how to develop the software to achieve the objectives defined in the BRD, use an FRD. This document describes how to implement features, design the user interface, and manage data requirements. It lays out the blueprint for developers to follow.
It’s important to note that both documents are not mutually exclusive – they work best when used together. The BRD provides a high-level view of the project, and the FRD provides a more detailed view of the requirements, ensuring all the team members involved in the project have a common understanding of the project goals, objectives, and technical requirements.
| BRD | FRD |
|---|---|
| Defines business requirements and scope of the project | Describes how to achieve the objectives defined in the BRD |
| Focuses on the business aspects of the project | Focuses on the technical aspects of the project |
| Provides a roadmap for the project | Provides a blueprint for developers to follow |
In conclusion, while both the BRD and FRD are important documents in software development, they differ in their focus and scope. Choosing which document to use depends on the goals and objectives of your project. By using both the BRD and FRD together, you can ensure all stakeholders have a common understanding of the project requirements, reducing the risk of misunderstandings and ensuring a successful project outcome.
Key Components of a BRD
A Business Requirement Document (BRD) is a comprehensive document that serves as a reference point in the development and implementation of a new project. Here are the key components of a BRD:
Objective
- The objective of a BRD is to clearly define the business need, scope, and objectives of the project being developed.
- The document helps in establishing the criteria for project success and provides a reference point throughout the project life-cycle.
- The objective is to gather all the requirements from various stakeholders and create a unified document that captures the goals and objectives of the project.
Functional Requirement
A functional requirement specifies what the project should do. It describes the inputs, processes, and outputs that are required to achieve the project objective. Functional requirements provide a clear understanding of the business logic and workflow of the system and serve as a basis for system testing.
Non-functional Requirement
A non-functional requirement specifies how the project should do it. This refers to the quality attributes such as reliability, performance, usability, security, and maintainability, amongst others. Non-functional requirements ensure that the system is not only useful but is also efficient, effective, and user-friendly.
Requirements Traceability Matrix (RTM)
A requirements traceability matrix (RTM) is a table that links the functional and non-functional requirements to their source, such as user needs, business objectives, or design documents. This matrix is used to track the requirements throughout the project life-cycle, ensuring that they are implemented as planned and tested successfully. The RTM also serves as a reference point to confirm that the delivered system meets all the defined requirements.
| Requirement ID | Requirement Statement | Source | Priority | Status |
|---|---|---|---|---|
| RQ-001 | The system should allow users to create a new account | User need | 1 | Implemented |
| RQ-002 | The system should allow users to reset their password | User need | 2 | Planned |
| RQ-003 | The system should encrypt user data | Security requirement | 1 | Implemented |
A requirements traceability matrix is a crucial component of a BRD, as it provides a clear reference point to track the requirements and ensure that they are implemented correctly.
Key Components of an FRD
In software development projects, a functional requirement document (FRD) is an essential tool for the development team to understand the scope of the project and the system requirements. An FRD is usually created after the business requirements document (BRD) and outlines the details of how the software should function.
The following are the key components of an FRD:
- Introduction: This section provides an overview of the project and the purpose of the FRD.
- Product Overview: This section describes the product in terms of its features, functionality, and expected benefits. It should include a high-level overview of the product.
- Functional Requirements: This section outlines the specific requirements that the software must meet in order to satisfy the project goals. It defines the functionalities, features, and capabilities needed to meet the users’ needs.
- Non-Functional Requirements: This section outlines the set of requirements that describe how the software should function. These requirements detail the usability, performance, security, flexibility, scalability, and reliability of the system.
- Technical Requirements: This section presents the technical specifications of the software, such as the hardware, software, network, and database requirements.
- Assumptions and Dependencies: This section outlines the assumptions and dependencies that may impact the development and implementation of the software.
- Constraints: This section presents any constraints or limitations that may affect the development and implementation of the software. Examples could include budget or time constraints.
Functional Requirements:
Functional requirements are the core components of an FRD. They outline the intended functionality of the software, what the software should do, and how it should behave in diverse scenarios. These requirements usually provide a detailed description of each feature and define how the user will interact with the system.
Functional requirements are applicable at different levels of the software development process. They can be classified into low-level or detailed requirements, and high-level requirements. Low-level requirements provide more detailed and specific functionality while a high-level captures a broader view of features or functions.
Functional requirements must be written such that the development team can understand them. They must provide clear instructions and unambiguous functionality that is required by the project stakeholders, including the users, developers, and testers. Furthermore, functional requirements should be linked to test scenarios to ensure that they can be validated through testing.
Non-Functional Requirements:
Non-functional requirements describe the system’s behavior and qualities in terms of how it should perform and function. In contrast to Functional Requirements, which outline what the system should do, non-functional requirements describe how the software should operate.
Non-functional requirements include descriptors such as the performance, reliability, security, usability, flexibility, and maintainability of the software. They define the interface between the user and the software system. It is important to emphasize that non-functional requirements are equally important as functional requirements and should be included in the FRD.
Technical Requirements:
Technical requirements describe the hardware and software infrastructure required for the software to function optimally. The technical requirements should be outlined with the aim of providing clear guidelines for the development team to implement and maintain the software system. The technical requirements encompass hardware requirements, software requirements, and network requirements.
| Component | Description |
|---|---|
| Hardware Requirements | This section outlines the hardware specifications needed for the software to run effectively. It includes details such as memory, processing power, and storage. |
| Software Requirements | This section outlines the software specifications needed for the software to run effectively. It includes details such as the operating system and language requirements. |
| Network Requirements | This section outlines the network specifications needed for the software to run effectively. It includes details such as bandwidth and network protocols needed for the software to communicate effectively. |
Technical requirements should be considered during early stages of the development process to avoid costly rework, ensure compliance with organizational standards, and ensure scalability.
Use Cases for BRD
