Understanding the BRD
Unlock Audio Lesson
Today, we'll focus on the Business Requirements Document or BRD. Can anyone tell me what the BRD is?
Isn’t it about the business needs of a project?
Exactly! The BRD outlines high-level business needs and objectives. Its main purpose is to define goals and initiate projects. What do you think are the key components of a BRD?
Could it include the business objectives and project scope?
Yes, that's correct! It also contains a stakeholder list and high-level requirements. So, remember the acronym EBSH - Executive Summary, Business Objectives, Stakeholder, and High-Level Requirements.
Can you give an example of a high-level requirement?
Sure! An example could be: 'The system shall allow customers to view previous transactions for up to 12 months.'
To recap, the BRD is essential for defining business goals and ensuring stakeholder alignment. Any questions?
Diving Into the FRD
Unlock Audio Lesson
Now let's discuss the Functional Requirements Document, or FRD. Who can brief me on what the FRD represents?
Is it about the technical functions of the system?
Correct! The FRD translates business needs into system functions. Its main purpose is to guide developers and QA teams. What key components do you think are included in an FRD?
Maybe use cases and functionality outlines?
Yes! It includes functional features, use case diagrams, data flow diagrams, etc. Here's a mnemonic to remember: FEUD - Functional Features, End-User Scenarios, User Stories, Data Flow. Can anyone provide an example of a functional requirement?
How about: ‘When a user clicks 'Download Invoice', the system generates a PDF?’
Spot on! The FRD is fundamental for establishing the 'what' of the system.
Exploring the SRS
Unlock Audio Lesson
Next, we examine the Software Requirements Specification or SRS. Who can explain its purpose?
Is it like a comprehensive guide that combines everything?
Exactly! The SRS encompasses both functional and non-functional requirements and is a reference for development and QA. What do you think are some non-functional requirements mentioned in SRS?
Things like performance, security, and usability?
Perfect! These aspects are critical as they define how the system behaves under certain conditions. Remember the acronym PURS for Performance, Usability, Reliability, Security. Can someone summarize the key components?
It includes functional requirements, non-functional requirements, and system interfaces!
Great summary! SRS documents are vital for ensuring clarity and completeness.

Quick Overview
Standard
The section discusses the critical role of requirements documentation in ensuring project success. It introduces three key documents: the Business Requirements Document (BRD), Functional Requirements Document (FRD), and Software Requirements Specification (SRS), detailing their purposes, components, and target audiences.
Detailed
Purpose of Requirement Documentation
Well-documented requirements act as a cornerstone for successful project execution. They facilitate alignment among all stakeholders, including business users and developers. This section elaborates on three fundamental types of requirement documents: BRD, FRD, and SRS.
1. Business Requirements Document (BRD)
- Definition: The BRD captures the high-level business needs and objectives.
- Purpose: To define goals, gain buy-in, and initiate projects.
- Key Components:
- Executive Summary
- Business Objectives
- Project Scope
- Stakeholder List
- High-Level Requirements
2. Functional Requirements Document (FRD)
- Definition: The FRD translates business needs into detailed specifications for the system's functionalities.
- Purpose: To guide developers and QA teams on the technical aspects of the system.
- Key Components:
- Functional Features
- Use Cases
- Data Flow Diagrams
3. Software Requirements Specification (SRS)
- Definition: The SRS incorporates both functional and non-functional requirements into one comprehensive document.
- Purpose: To serve as a single reference point for all stakeholders involved in the development and quality assurance.
- Key Components:
- Functional and Non-Functional Requirements
- System Interfaces
- Traceability Matrix
In summary, these documents not only facilitate project clarity but also ensure cohesive communication among the various stakeholders involved.

Purpose of the Business Requirements Document (BRD)
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
● To define business goals and scope
● To get executive/stakeholder buy-in and sign-off
● To initiate the project and establish a shared understanding
Detailed Explanation
The purpose of the Business Requirements Document (BRD) is multifaceted. First, it defines the business goals and scope, meaning it indicates what the project aims to achieve and the boundaries within which it operates. Second, the BRD is crucial for gaining support and approval from executives and stakeholders. They need to understand and agree on what the project entails before it can move forward. Lastly, the BRD helps to kick off the project by creating a shared understanding among all participants, ensuring everyone is on the same page regarding the objectives and expectations.
Examples & Analogies
Imagine planning a team vacation. The BRD would be like the initial itinerary that outlines where you want to go (business goals), the budget (scope), and gets the agreement from all team members (buy-in). Without this document, confusion might arise about the destination or costs involved, leading to disagreements and lack of enthusiasm.
Key Components of the BRD

● Executive Summary / Introduction
● Business Objectives
● Project Scope (In-scope and Out-of-scope)
● Stakeholder List
● High-Level Business Requirements
● Assumptions and Constraints
● Success Criteria
Detailed Explanation
The BRD consists of several key components that work together to ensure clarity and comprehensiveness. The Executive Summary provides an overview of the document, while the Business Objectives section outlines what the organization wishes to accomplish. The Project Scope defines what is included and what is not. It's important to have a clear Stakeholder List to identify who is involved and impacted. The High-Level Business Requirements give specific details about what needs to be achieved. Assumptions and Constraints clarify what is taken for granted and any limitations faced by the project. Lastly, the Success Criteria establish how the project's success will be measured.
Examples & Analogies
Using the vacation analogy, the Executive Summary would be a brief overview of the proposed trip. The Business Objectives might include having fun and experiencing local culture. Project Scope would describe what activities are planned, while the Stakeholder List includes everyone going on the trip. High-Level Business Requirements could specify booking accommodations and flights, while Assumptions might state that everyone can take time off work, and Constraints could be that the budget is limited. Success Criteria might include enjoying the trip without any major issues.
Example Business Requirement

Example Business Requirement:
“The system shall allow customers to view previous transactions for up to 12 months.”
Detailed Explanation
An example of a business requirement clarifies what needs to be in place from a functional perspective. It is specific and measurable, indicating that customers should have access to their transaction history for a defined period. This requirement helps the developers understand exactly what feature is expected and sets a clear expectation for stakeholders about what the end system will provide.
Examples & Analogies
Think of this like a bank app where customers can look at their recent purchases. Just as the bank specifies, 'you can see all your transactions for the last year,' the business requirement clearly communicates to the development team what needs to be built. This ensures users can feel confident about tracking their finances.
