"The system should have a fast response time" is an example of what type of requirement?

The statement "The system should have a fast response time" exemplifies an unbounded requirement. An unbounded requirement lacks a clear and quantifiable criterion for what constitutes "fast." Without specifying measurable parameters, such as response times in milliseconds or seconds under certain conditions, the requirement remains vague and open to interpretation.

This ambiguity can lead to various interpretations by stakeholders, which may result in misaligned expectations during the development process. By not defining what "fast" means, the requirement fails to provide the necessary guidance for designers and developers to implement an accurate solution that meets the users' needs effectively. Clear and bounded requirements are crucial in systems engineering to ensure that end products meet stakeholder expectations and perform as intended.
