How do you distinguish a business requirement from a functional requirement? Provide an example in one case.

A business requirement describes what the business aims to achieve, its goals, and value, while a functional requirement specifies the particular functions or behaviors of the system that implement these goals.

Example in the case of an online store:

• Business requirement: "Increase customer conversion by simplifying the checkout process."
• Functional requirement: "The system should allow the user to place an order in one click, using saved payment and delivery data."

Thus, the business requirement focuses on the goal and outcome, while the functional requirement focuses on the specific implementation that helps achieve this goal.
