A transit authority's on-time performance is falling, and operations blames the vehicle fleet. The CHRO overlays operator vacancy and extra-board depth on the same KPI chart. What is the purpose of that overlay?
Select an answer to reveal the explanation.
Short Explanation
If buses are late, counting only broken engines is like blaming the oven when nobody showed up to bake. Extra-board depth and operator vacancies sit on the same clock as the vehicles. Overlaying those people numbers shows whether the strategy is slipping for lack of drivers, not just lack of buses.
Full Explanation
Strategic KPIs mislead when a single operational story is allowed to explain them. On-time performance is jointly produced by fleet availability and operator coverage, including extra-board depth that absorbs absences. Overlaying vacancy and extra-board on the same chart tests whether people gaps are the hidden driver. SPHR metric use is diagnostic: combine operational and workforce measures so leadership treats the real constraint.
