Maintenance Technician Utilization at 81% utilization target: a worked example
This scenario runs the maintenance technician utilization calculation on the strong side: 81% utilization target, with every other input held at its documented default. Use it when trying to improve wrench time, crew loading, and schedule compliance without overbooking the craft team.
The inputs for this scenario
- Wrench time: 5.5 hr (unchanged)
- Available shift hours: 8 hr (unchanged)
- Utilization target: 81 % (raised for this scenario; the documented default is 70)
Working through the calculation
- Applying the documented formula (Technician utilization = wrench time ÷ available shift hours × 100) to the inputs above produces each figure below.
- At this operating point the engine returns 68.75 % for technician utilization, the number this scenario is built around.
- At this operating point the engine returns 12.25 points for gap to utilization target.
- At this operating point the engine returns 5.5 value for wrench time.
- At this operating point the engine returns 8 value for available shift time.
How this compares with the baseline
- Against the tool's baseline example, where utilization target sits at 70% and the headline result is 68.75 %, this scenario lands almost exactly on the baseline at 68.75 %.
- Use it after a wrench-time study or work-sampling exercise to quantify how productively shift time is being used and where you stand against goal. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
