Business Requirements Document (BRD)
Unlock Audio Lesson
Today, we're discussing the Business Requirements Document, or BRD. Can anyone tell me what a BRD typically outlines?
It outlines the business needs and objectives, right?
Exactly! It's crucial because it addresses the 'Why' and 'What' of the project. Now, what do you think is the importance of having a stakeholder list in the BRD?
It helps to identify who is involved or impacted by the project.
Great point! This alignment ensures everyone has a shared understanding. Remember the acronym SMART for objectives - Specific, Measurable, Achievable, Relevant, Time-bound. Can anyone give me an example of a high-level business requirement?
The system shall allow customers to view previous transactions for up to 12 months.
Perfect example! Let's summarize: the BRD helps define goals, gain buy-in, and initiate projects.
Functional Requirements Document (FRD)
Unlock Audio Lesson
Next, we have the Functional Requirements Document, or FRD. What do we think it defines?
It translates business needs into specific functionalities of the system.
Exactly! It acts as a guide for developers. Can anyone explain what a use case diagram is?
It's a visual representation showing how users will interact with the system.
Correct! And use cases help clarify functional features. What about acceptance criteria?
Acceptance criteria specify conditions under which a feature is considered complete.
Right! So in conclusion, the FRD guides how the system should perform and provides detailed functionalities.
Software Requirements Specification (SRS)
Unlock Audio Lesson
Finally, we have the Software Requirements Specification, or SRS. What makes it different from the BRD and FRD?
It combines both functional and non-functional requirements.
Exactly! This presents a complete picture for engineers and QA teams. What do we mean by non-functional requirements?
They specify criteria that judge the operation of a system, like performance and security.
Great explanation! Remember, the SRS serves as a single reference for development and ensures all requirements are clearly stated. Let’s summarize the key points from today.

● Executive Summary / Introduction
Detailed Explanation
The Executive Summary or Introduction is crucial as it sets the stage for the entire document. It provides a brief overview of the project, allowing stakeholders to understand the key motivations behind the requirements presented in the document. It highlights the project’s objectives and the overall direction, ensuring everyone is on the same page right from the start.
Examples & Analogies
Think of the Executive Summary like the opening chapter of a story. Just as a good opening grabs your interest and gives you a glimpse of what’s to come, this summary draws stakeholders into understanding the project’s purpose and significance.
Business Objectives

● Business Objectives
Detailed Explanation
Business Objectives outline the specific goals that the project aims to achieve. These objectives are measurable and provide a clear direction for evaluating the project's success. They help align the stakeholders’ expectations and ensure that the requirements created subsequently will lead to an outcome that fulfills the organization's needs.
Examples & Analogies
Imagine a person setting out on a road trip. Without a destination (business objectives), they might drive around aimlessly. Business objectives act like a GPS, providing clarity on where the project should go and what it should accomplish.
Project Scope

● Project Scope (In-scope and Out-of-scope)
Detailed Explanation
Project Scope clearly defines what is included in the project (in-scope activities) and what is not (out-of-scope activities). This distinction is vital to prevent scope creep, where unplanned features may be added later that could derail the project. A well-defined scope ensures that resources are appropriately allocated to prioritize the core objectives.
Examples & Analogies
Consider a recipe for a cake. If the recipe states that it’s only for a chocolate cake, adding ingredients for a different cake (out-of-scope) would lead to a confused chef. Similarly, defining project scope keeps the team focused on achieving the intended outcome without deviations.
Stakeholder List

● Stakeholder List
Detailed Explanation
A Stakeholder List identifies all those involved in the project, including their roles and responsibilities. Recognizing stakeholders is key because it allows project teams to engage with the right people at the right times to gather feedback, facilitate approvals, and ensure that project outcomes meet their needs and expectations.
Examples & Analogies
Think of a movie crew. The director, actors, producers, and writers all play different roles. If the director forgets or overlooks a critical crew member, such as a sound engineer, the final product may suffer. In projects, knowing who the stakeholders are ensures a comprehensive approach to managing input and feedback.
High-Level Business Requirements

● High-Level Business Requirements
Detailed Explanation
High-Level Business Requirements provide a broad overview of what the system needs to achieve. They are not detailed but give a foundational understanding of the functional objectives that the system must fulfill. This section helps guide detailed requirements later in the process and ensures alignment with the initial business goals.
Examples & Analogies
Imagine building a house. The High-Level Business Requirements would be akin to the blueprint that outlines the number of rooms and overall layout without going into the specifics of paint colors or furniture arrangements. It provides a necessary framework for subsequent, more detailed planning.
Assumptions and Constraints

● Assumptions and Constraints
Detailed Explanation
Assumptions and Constraints identify key conditions or limits that impact the project. Assumptions are beliefs taken to be true without proof, while constraints are restrictions that the project must work within. Acknowledging these helps set realistic expectations and facilitates proactive planning to mitigate potential risks.
Examples & Analogies
Think of planning a picnic. You might assume that the weather will be nice and that everyone will be available to attend (assumptions). However, if you have to leave the picnic at 3 PM (constraint), planning activities accordingly is essential to make the most out of limited time.
Success Criteria

● Success Criteria
Detailed Explanation
Success Criteria define the measures by which the project’s success will be evaluated. Clear criteria help in making objective assessments of whether the project outcomes meet stakeholder expectations or business objectives. These criteria also guide the testing and validation process to ensure the project delivers as intended.
Examples & Analogies
In a sports game, success criteria might include scoring a certain number of points to win. Just as teams measure their success against a clear set of goals, projects use success criteria to evaluate their achievements and areas for improvement.
