Which of the following is an example of a quantified requirement for an auto repair shop?

A quantified requirement is one that is defined with specific, measurable parameters that can be objectively assessed. In this context, the statement regarding the wait time for pick-up being limited to a maximum of 30 minutes is an example of a quantified requirement because it provides a clear, numerical target that can be tracked and measured.

This allows the auto repair shop to gauge their performance against this specific standard. If customers wait longer than 30 minutes, it is easy to identify this as an area needing improvement, thus making it actionable for management.

In contrast, the other options, while potentially important to the operation of an auto repair shop, are not quantifiable in a precise manner. For example, saying the cost of service must be competitive does not specify how competitive it needs to be, or in what context. Likewise, stating that the quality of repairs must be high is subjective and lacks a measurable point of assessment, as is the idea that customer service must be friendly without defining what "friendly" entails or how it can be measured.
