What is an example of a performance requirement for a student records system?

The selection of a performance requirement focuses on the specific expectations related to how quickly and efficiently the system operates under certain conditions. In the context of a student records system, the requirement for the system to produce class lists within five hours after the end of registration directly addresses performance metrics. This sets a clear expectation for the system's speed and responsiveness in processing data following a critical event, which is integral for timely decision-making and operational effectiveness.

Performance requirements like this one are essential, as they define measurable outcomes that the system should consistently achieve, thereby ensuring that it meets users' needs within a defined timeframe. In this case, the emphasis is on the actual time taken to deliver functionality, which is a key aspect of performance metrics in system requirements.
