Today, weβre focusing on the BRD, or Business Requirements Document. Can anyone tell me its main purpose?
Is it to define project goals?
Exactly! The BRD outlines high-level business needs and objectives. It essentially answers the 'Why' and 'What' of the project, helping stakeholders align.
What are some key components of the BRD?
Great question! It includes an executive summary, business objectives, project scope, and a stakeholder list, among others. Remember the acronym **EBS - Executive, Business, Scope** to help memorize them!
How does it help in getting buy-in?
The BRD establishes a shared understanding of project goals, which is crucial for gaining stakeholder approval. Let's summarize: the BRD defines goals, shapes scope, and secures buy-in.
Functional Requirements Document (FRD)

Now, moving on to the FRD. Can anyone explain what an FRD does?
Is it more technical than the BRD?
Yes! The FRD translates business needs into technical functionalities. It details how a system should respond to user inputs.
What are some components of the FRD?
Key components include functional features, use case diagrams, and business rules. Remember, **FUB - Features, Use Cases, Business Rules** helps you recall them.
Why is it important for developers?
It provides a guideline for developers and testers, helping ensure that the system meets defined functionalities. To summarize, the FRD is crucial for mapping out what the system should do.
Software Requirements Specification (SRS)

Finally, letβs cover the SRS. Whatβs different about this document compared to the BRD and FRD?
It combines both functional and non-functional requirements.
Correct! The SRS provides a comprehensive view that is more technical, often prepared for handovers. It ensures clarity and completeness, guiding engineering teams.
What kind of non-functional requirements does it include?
Excellent! Non-functional requirements could include performance, security, usability, and reliability. You can remember them as **PSUR - Performance, Security, Usability, Reliability**.
So it acts like a blueprint for development?
Absolutely! To sum up, the SRS serves as the blueprint for developers and QA, integrating all requirements into a single reference document.
Introduction & Overview
Read summaries of the section's main ideas at different levels of detail.
Quick Overview
Standard
The purpose of requirement documents such as the BRD, FRD, and SRS is to clearly outline business and functional needs, ensuring alignment among stakeholders and guiding project implementation effectively.
Detailed
Purpose of Requirement Documents
Well-documented requirements are vital for the success of any project as they provide a clear foundation from which all stakeholders can work together. The Business Analyst plays a crucial role in creating these documents, ensuring alignment among business users, developers, and sponsors. This section will delve into the specific purposes of three essential requirement documents: the Business Requirements Document (BRD), the Functional Requirements Document (FRD), and the Software Requirements Specification (SRS).
Key Points:
- BRD - Business Requirements Document: Outlines high-level business needs and objectives, defining the project scope and securing stakeholder buy-in.
- Purpose: To establish business goals, gain approvals, and ensure a shared understanding of the project.
- Key Components: Executive summary, business objectives, project scope, stakeholder list, etc.
- FRD - Functional Requirements Document: Translates business needs into detailed functionalities of the system, serving as a blueprint for developers.
- Purpose: To guide technical teams on what the system should do in response to specific user interactions.
- Key Components: Functional features, use case diagrams, business rules, etc.
- SRS - Software Requirements Specification: Merges both functional and non-functional requirements, acting as a comprehensive document for engineers and vendors.
- Purpose: To ensure clarity and completeness, providing a single point of reference for development and quality assurance.
- Key Components: System overview, functional requirements, non-functional requirements (e.g., performance, security), etc.
By understanding the distinct purposes each document serves, stakeholders can better appreciate their roles throughout the project lifecycle.

β To define business goals and scope
β To get executive/stakeholder buy-in and sign-off
β To initiate the project and establish a shared understanding
Detailed Explanation
The purpose of the Business Requirements Document (BRD) is multi-faceted. First, it defines the business goals and scope of the project, which outlines what the project aims to achieve and what will be included in its scope. Second, the BRD aims to secure executive and stakeholder buy-in and sign-off, meaning it helps to get approval from those who have a vested interest in the project. Lastly, it serves to initiate the project and establish a shared understanding among all stakeholders involved, ensuring everyone is on the same page about what the project entails.
Examples & Analogies
Think of the BRD like a blueprint for building a house. Before construction begins, the builder needs to know the homeowner's goals (like having three bedrooms and two bathrooms), get approval from the homeowner, and ensure that everyone involved in the project understands what the house will look like and what will be included in the construction.

Chapter Content
β To serve as a guide for developers and QA teams
β To define the βwhat the system should doβ in technical terms
Detailed Explanation
The Functional Requirements Document (FRD) serves as a technical guide for developers and quality assurance (QA) teams working on the project. It clearly outlines the 'what the system should do,' providing detailed functionalities and behaviors of the system. This document translates the high-level business needs from the BRD into specific requirements that developers must follow during the system's design and implementation.
Examples & Analogies
Imagine you are following a recipe to bake a cake. The FRD is like the recipe that tells you exactly what ingredients you need and how to mix them. Without it, the bakers (developers) might not know how to create the desired cake (system), leading to a product that doesnβt meet the expectations laid out in the BRD.
Purpose of the SRS
Chapter 3 of 3

Chapter Content
β To serve as a single reference point for development and QA
β To ensure clarity, completeness, and testability of the system
Detailed Explanation
The Software Requirements Specification (SRS) combines both functional and non-functional requirements into one comprehensive document. It serves as a single reference point for development and QA teams, ensuring that everyone involved understands both the specifications for how the system should behave and additional requirements like performance and security. The SRS ensures that the document is clear, complete, and testable, meaning that the success criteria for the project can be effectively measured.
Examples & Analogies
Think of the SRS like a complete instruction manual for assembling furniture. It not only shows you how each piece fits together (functional requirements) but also details quality standards and safety checks to ensure the final product is sturdy and reliable (non-functional requirements). Without such a manual, you might end up with a wobbly chair instead of a sturdy table!
Key Concepts
-
BRD: Outlines high-level business needs and secures stakeholder buy-in.
-
FRD: Translates business requirements into detailed functionalities of a system.
-
SRS: Comprehensive document integrating functional and non-functional system requirements.
Examples & Applications
Example of a BRD: 'The system shall allow customers to view previous transactions for up to 12 months.'
Example of an FRD: 'When a user clicks βDownload Invoiceβ, the system should generate a PDF with billing details.'
Example of an SRS: 'The application shall support up to 10,000 concurrent users with a response time of less than 3 seconds.'
Memory Aids
Interactive tools to help you remember key concepts
Rhymes
BRD outlines scope with care, FRD shows what the system will share, SRS blends both into a tech affair.
Stories
Imagine a project where the team starts with the BRD to define their goals. Then, they move to the FRD, like translating a language to make sure developers know what to build. Finally, with SRS, they have a complete guide, almost like a recipe for success.
Memory Tools
Remember B, F, S: BRD for 'Business', FRD for 'Functional', SRS for 'Software'.
Acronyms
Use **EBS** for BRD (Executive, Business Objectives, Scope), and **FUB** for FRD (Features, Use Cases, Business Rules).
