What is a Requirement? And Why it Matters in Business Analysis

Defining Requirements in Business Analysis
📌 A requirement is defined as a clear description of what a user wants or needs in a solution, ensuring the final product is usable and effective.
🧵 The video uses the analogy of visiting a tailor where unclear descriptions ("smart and traditional") lead to receiving the wrong item (a full aada instead of a simpler capan).
🔍 In business analysis, clarifying requirements helps determine that the right solution is being built, preventing wasted effort on unnecessary features.

Types of Requirements
📊 Business Requirements: These are big-picture goals that answer "Why are we doing this project?" (e.g., a hospital aiming to reduce patient wait times by 40% this year).
🧑‍⚕️ Stakeholder Requirements: These detail the specific needs of relevant individuals, such as a receptionist needing a quicker way to register patients or a doctor wanting to see lab results in real time.
⚙️ Functional Requirements: These specify what the solution must actually do, covering concrete features like the system allowing patients to book appointments online or the app sending SMS reminders.
⏱️ Nonfunctional Requirements: These concern the quality of the system—how it performs its functions (e.g., the website must load in 3 seconds or accommodate 10,000 users concurrently).

Application Example (SwiftKart)
🚀 Business Requirement Example: SwiftKart aims to reduce average delivery time from 2 hours to 45 minutes within Lagos.
📍 Stakeholder Requirements Example: Customers want real-time delivery updates, and drivers need routes that avoid traffic.
📡 Nonfunctional Requirement Example: The system must display updates even with low or unstable mobile data connections.

Key Points & Insights
➡️ The role of a Business Analyst is crucial to capture, clarify, and record different requirement types because assumptions lead to disasters in project execution.
➡️ Avoid building solutions nobody needs by confirming and clarifying requirements across all relevant industries (health, construction, tech).
➡️ Functional requirements define the features developers build, whereas nonfunctional requirements define the performance and quality attributes of the solution.
