A company calls its helpline and measures the average time to answer calls. Management wants to use this single non-financial indicator to assess customer service. Which limitation is MOST relevant?

The main limitation is dysfunctional behaviour: staff may rush or end calls early to improve the time measure, reducing the quality of resolution. The measure is quantifiable and timely, so the other options are incorrect.

  1. AIt may encourage staff to end calls quickly, harming resolution qualityCorrect
  2. BIt cannot be quantified and so cannot be compared over time
  3. CIt is only available after the year-end financial statements are prepared
  4. DIt measures only past financial results

Explanation

Focusing on a single speed metric can lead to dysfunctional behaviour such as rushing or cutting off callers, reducing quality. Such measures are quantifiable, available promptly and non-financial, so the other options are wrong.
