Non-functional Requirements

Non-Functional Requirements are the qualities and constraints of a system that define how it should operate rather than what it should do. These include aspects like performance, security, usability, and reliability. For example, a website might need to load in under three seconds, be secure against attacks, and be easy for users to navigate. While functional requirements specify the tasks a system must perform, non-functional requirements ensure it meets standards that enhance user experience and overall effectiveness. Together, they contribute to the system's overall success and satisfaction.
