What represents non-functional requirements?

• A. What the system must do
• B. How the system should perform
• C. The stakeholders involved with the system
• D. The budget allocated for the project

Answer: (B)

Non-functional requirements specifically refer to how a system should perform rather than what it does. They encompass various attributes such as performance, security, usability, reliability, and scalability. These requirements define the quality and effectiveness of the system, focusing on user experience and system constraints rather than the specific functions or features the system must deliver. This distinction is crucial in requirements management because while functional requirements detail the actions a system must complete, non-functional requirements shape its operational context, influencing user satisfaction and overall success. Non-functional requirements help to ensure that the system not only meets the intended functionality but also performs well under expected conditions and satisfies user needs in a broader sense.
