Next, let’s discuss the FRD. What do you think it's for?
Isn’t it about detailing how the system functions?
Exactly! The FRD translates business needs into technical details. Can anyone mention what components it includes?
It has use case diagrams and acceptance criteria!
Correct! It guides the developers by clearly defining the system's behavior. How does this help in the development process?
It helps avoid misunderstandings, making sure developers know what to build.
Understanding the SRS
Unlock Audio Lesson
Finally, let’s look at the SRS. Who can tell me what makes it different from the BRD and FRD?
It combines both functional and non-functional requirements, right?
Exactly! The SRS is a comprehensive document serving as a blueprint. What types of non-functional requirements can you think of?
Things like performance and security?
Correct! It’s crucial for ensuring clarity and completeness in the development process.
Comparing All Documents
Unlock Audio Lesson
Now that we've covered each document, how do you think they relate to each other?
They build on each other — the BRD informs the FRD, which leads to the SRS.
Precisely! This traceability ensures that every requirement is captured and validated throughout the project. What’s a good practice for maintaining these documents?
Version control is important!
Exactly! Keeping track of updates helps maintain clarity among stakeholders.

The table summarizes the three types of requirement documents: BRD, FRD, and SRS.
Detailed Explanation
This chunk introduces a table that compares three types of requirement documents used in project management: the Business Requirements Document (BRD), Functional Requirements Document (FRD), and the Software Requirements Specification (SRS). Each document serves a distinct purpose and is meant for different audiences, emphasizing the unique focus areas and the intended users of each document.
Examples & Analogies
Think of these three documents as different maps for a trip. The BRD acts like a roadmap showing the overall destination and key landmarks (business needs), the FRD provides detailed directions and routes for the journey (specific functionalities), while the SRS includes travel tips and necessities for the journey like rest stops and gas stations (comprehensive specifications).

| FRD | System’s functional behavior | Business Analyst (with Devs) | Developers, Testers | Detailed features, use cases |
Detailed Explanation
The FRD details the functional behavior of the system, serving as a bridge between business needs and technical design. It's crafted by the Business Analyst in collaboration with developers and is primarily used by developers and testers. It outlines the specific functionalities and use cases that the system must deliver to fulfill business requirements.
Examples & Analogies
Continuing the wedding analogy, the FRD would represent the detailed checklist of tasks needed for the wedding. This might include the specific decorations, catering options, and the order of events, providing direction on how to actualize the vision set forth by the BRD.
SRS - Software Requirements Specification

This document is typically crafted by both a Business Analyst and system architects and serves as a reference for the developers, quality assurance teams, and vendors involved in the project.
Examples & Analogies
Using the wedding plan once more, the SRS is analogous to a detailed itinerary for the day of the wedding. Like an itinerary outlines every element including timing, roles of individuals, and specific tasks, the SRS outlines every requirement the system must meet to ensure the project runs smoothly and everyone knows their responsibilities.
