What is the focus of nonfunctional requirements in system development?

The focus of nonfunctional requirements in system development emphasizes the overall system characteristics that define how the system should behave and operate rather than what specific functionalities it must provide. Nonfunctional requirements encompass a wide range of criteria such as performance, usability, reliability, security, and maintainability, ensuring that the system meets broader quality standards and operational Constraints.

In contrast, specific functionalities relate directly to the features or tasks a system must accomplish, while system performance and user interface design are more specific aspects under the broader umbrella of nonfunctional requirements. Therefore, by selecting the focus on overall system characteristics, it captures the essence of nonfunctional requirements as it addresses the system's attributes that contribute to its effectiveness and user satisfaction.
