Customer Acceptance Cycle Time at 32% customer review and retest allowance: a worked example

This worked example runs the customer acceptance cycle time numbers for a tougher week than the baseline: 32% customer review and retest allowance instead of the typical 45%. Estimate customer acceptance cycle time from open acceptance items, closeout throughput, and review allowance.

The inputs for this scenario

  • Open acceptance items: 38 items (held at the documented default)
  • Acceptance closeout throughput: 4 items / hr (held at the documented default)
  • Customer review and retest allowance: 32 % (the input this scenario stresses; the baseline uses 45)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base customer acceptance time = open acceptance items รท acceptance closeout throughput.
  • Required customer acceptance cycle time works out to 12.54 hr at these inputs, and this is the headline figure for the scenario.
  • Base customer acceptance time works out to 9.5 hr at these inputs.
  • Customer review and retest allowance works out to 32 % at these inputs.
  • Acceptance closeout throughput works out to 4 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where customer review and retest allowance sits at 45% and the headline result is 13.78 hr, this scenario comes in 8.97% below the baseline at 12.54 hr.
  • Use it during FAT/SAT planning, commissioning closeout, or when forecasting a handover or ship date against an open punch list. 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

  • Required customer acceptance cycle time: 12.54 hr (headline result)
  • Base customer acceptance time: 9.5 hr
  • Customer review and retest allowance: 32 %
  • Acceptance closeout throughput: 4 pieces / min
