Customer Acceptance Cycle Time at 52% customer review and retest allowance: a worked example

What does the result look like when customer review and retest allowance reaches 52%? The full calculation is worked below with real intermediate numbers. Use it when managing punch lists, acceptance documents, customer comments, and final signoff for machinery projects.

The inputs for this scenario

  • Open acceptance items: 38 items (unchanged)
  • Acceptance closeout throughput: 4 items / hr (unchanged)
  • Customer review and retest allowance: 52 % (raised for this scenario; the documented default is 45)

Working through the calculation

  • Applying the documented formula (Base customer acceptance time = open acceptance items รท acceptance closeout throughput) to the inputs above produces each figure below.
  • At this operating point the engine returns 14.44 hr for required customer acceptance cycle time, the number this scenario is built around.
  • At this operating point the engine returns 9.5 hr for base customer acceptance time.
  • At this operating point the engine returns 52 % for customer review and retest allowance.
  • At this operating point the engine returns 4 pieces / min for acceptance closeout throughput.

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 4.83% above the baseline at 14.44 hr.
  • A figure at this level is achievable when customer review and retest allowance is genuinely sustained, not just peaked for a shift. It assumes items clear at a steady rate, but customer-driven review and retest loops are bursty and can stall on a single contested item beyond what the allowance captures.

Results at a glance

  • Required customer acceptance cycle time: 14.44 hr (headline result)
  • Base customer acceptance time: 9.5 hr
  • Customer review and retest allowance: 52 %
  • Acceptance closeout throughput: 4 pieces / min
