Depot Repair Yield at 66% target depot repair yield: a worked example

This worked example runs the depot repair yield numbers for a tougher week than the baseline: 66% target depot repair yield instead of the typical 92%. Calculate accepted depot repair yield from repaired units passing final test, total repair attempts, and the yield target.

The inputs for this scenario

  • Repaired units passing final test: 138 units (held at the documented default)
  • Depot repair attempts: 162 attempts (held at the documented default)
  • Target depot repair yield: 66 % (the input this scenario stresses; the baseline uses 92)

Working through the calculation

  • The calculation starts from the formula this tool documents: Depot repair yield = repaired units passing final test ÷ depot repair attempts × 100.
  • Depot repair yield works out to 85.19 % repair yield at these inputs, and this is the headline figure for the scenario.
  • Repair yield gap works out to -19.19 percentage points at these inputs.
  • Units passing final test works out to 138 units at these inputs.
  • Depot repair attempts works out to 162 attempts at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target depot repair yield sits at 92% and the headline result is 85.19 % repair yield, this scenario lands almost exactly on the baseline at 85.19 % repair yield.
  • Use it per product line, per depot, or per technician group to judge how reliably a repair process restores units to serviceable condition. 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

  • Depot repair yield: 85.19 % repair yield (headline result)
  • Repair yield gap: -19.19 percentage points
  • Units passing final test: 138 units
  • Depot repair attempts: 162 attempts
