What is an example of a non-functional requirement?

• A. Functionality of the system
• B. Performance metrics such as response time
• C. System integration capabilities
• D. User interface design

Answer: (B)

A non-functional requirement refers to criteria that can be used to judge the operation of a system, rather than specific behaviors or functions. Performance metrics, such as response time, define how well a system performs its functions under certain conditions. They focus on the qualities of the system, including speed, efficiency, reliability, and scalability, rather than describing specific features or capabilities. In contrast to non-functional requirements, elements related to functionality, such as the core actions a system must perform, do not fall under this category. Similarly, capabilities concerning system integration or design elements of the user interface focus more on what the system can do and how it looks, rather than how well it performs those functions. Thus, performance metrics like response time distinctly categorize as non-functional requirements, emphasizing the operational performance aspects of the system.
