True or False: Non-functional requirements are constraints on functional requirements.

True or False: Non-functional requirements are constraints on functional requirements.

• A. True
• B. False
• C. They are unrelated to functional requirements
• D. They are only about performance

Answer: (A)

Non-functional requirements describe how the system should behave and perform, specifying quality attributes such as performance, security, reliability, maintainability, usability, and scalability. These attributes act as constraints on how the functional requirements are implemented and delivered. They determine how fast a function must respond, how much load it can handle, how secure it must be, and other standards the system must meet. In that sense, non-functional requirements constrain the way functional requirements are satisfied, shaping the overall behavior and quality of the system. They are not unrelated to functional requirements, and they cover more than just performance. So the statement is true.
