Legal or regulatory requirements can be classified under which type of requirements?

Legal or regulatory requirements fall under non-functional requirements because they specify constraints or conditions that the system must satisfy but do not define specific behaviors or functions of the software. Non-functional requirements address how the system should perform and include aspects like security, reliability, compliance with legal standards, and performance metrics.

In the context of software development, while functional requirements define the specific operations and functionality of the system (like user authentication or data processing), non-functional requirements ensure that the system adheres to legal standards, industry regulations, and compliance requirements, which are critical for protecting user data and maintaining brand integrity. This classification emphasizes the importance of building systems that are not only efficient and effective but also compliant with laws that govern operations in various sectors.
