Aftermarket, Field Service & Service Parts worked example

Technician Utilization at 56% target technician utilization: a worked example in aftermarket, field service & service parts

This worked example runs the technician utilization numbers for a tougher week than the baseline: 56% target technician utilization instead of the typical 78%. Calculate productive technician utilization from billable or assigned service hours, available technician hours, and a utilization target.

The inputs for this scenario

  • Productive technician service hours: 2,860 hr (held at the documented default)
  • Available technician hours: 3,600 hr (held at the documented default)
  • Target technician utilization: 56 % (the input this scenario stresses; the baseline uses 78)

Working through the calculation

  • The calculation starts from the formula this tool documents: Technician utilization = productive service hours ÷ available technician hours × 100.
  • Technician utilization works out to 79.44 % utilization at these inputs, and this is the headline figure for the scenario.
  • Utilization gap to target works out to -23.44 percentage points at these inputs.
  • Productive service hours works out to 2,860 hr at these inputs.
  • Available technician hours works out to 3,600 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target technician utilization sits at 78% and the headline result is 79.44 % utilization, this scenario lands almost exactly on the baseline at 79.44 % utilization.
  • Use it at the end of each week or month to grade an individual tech, a crew, or a branch, and during capacity planning before you add or cut a route. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance
