Which of the following processes describes the elements such as quantity, quality, coverage, timelines, and availability, and categorizes the different functions that the system will need to perform…

Human factors (or ergonomics) relate to the interaction between humans and systems, focusing on user experience and safety, not the system's core functions.

Functional requirements describe the functions that a system or component must be able to perform, defining what the system does to meet documented mission or business needs. These elements, such as quantity (of functions), quality (of output), coverage (of tasks), and availability (of services), contribute to defining the overall system functionality.

Performance requirements specify how well the system performs its functions, often including metrics like speed, response time, and throughput, which are separate from what functions it performs.

Operational scenarios describe specific sequences of events or interactions the system will undergo in a particular operational context, illustrating how functions are used, but not defining the functions themselves.
