What are functional requirements best defined as?

Those processes that you want a system to perform.
The attributes of the system as a whole or its environment.
The requirements needed for the hardware to function.
The expected outcomes of a system's performance.

The correct answer is: Those processes that you want a system to perform.

Functional requirements are best defined as the specific processes, tasks, or functions that a system must be able to perform in order to meet the needs of its users. They outline what the system should do and describe actions that the system must take. This includes things like user interactions, business rules, and data processing specifications that collectively ensure the system will fulfill its intended purpose. By clearly articulating the desired capabilities of the system, functional requirements serve as a foundation for system design, development, and testing. The other choices do not capture the essence of functional requirements. The attributes of the system as a whole or its environment refer more to non-functional requirements, which focus on how a system behaves rather than what it does. The requirements needed for hardware to function relate to hardware specifications and capabilities rather than functional actions of the system itself. Expected outcomes of a system's performance generally align more with performance metrics or success criteria, which are usually categorized as non-functional requirements, as they describe results rather than specific functionalities.
