Repair Turnaround Time at 47% queue, test, and paperwork allowance: a worked example

This worked example runs the repair turnaround time numbers for a tougher week than the baseline: 47% queue, test, and paperwork allowance instead of the typical 65%. Estimate repair turnaround hours from repair orders, completion pace, and queue, test, or paperwork allowance.

The inputs for this scenario

  • Repair orders in queue: 72 orders (held at the documented default)
  • Repair completion pace: 0.28 orders/min (held at the documented default)
  • Queue, test, and paperwork allowance: 47 % (the input this scenario stresses; the baseline uses 65)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base repair processing time = repair orders รท repair completion pace.
  • Repair turnaround time works out to 378 turnaround hr at these inputs, and this is the headline figure for the scenario.
  • Base repair processing time works out to 257 turnaround hr at these inputs.
  • Queue, test, and paperwork allowance works out to 47 % at these inputs.
  • Repair completion pace works out to 0.28 orders/min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where queue, test, and paperwork allowance sits at 65% and the headline result is 424 turnaround hr, this scenario comes in 10.91% below the baseline at 378 turnaround hr.
  • Use it when quoting turnaround time to a customer, sizing repair-bench staffing, or forecasting when a growing queue will breach your service-level target. 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.
