Quality Inspection Load at 7.2% hold, recheck, and documentation allowance: a worked example

This worked example runs the quality inspection load numbers for a tougher week than the baseline: 7.2% hold, recheck, and documentation allowance instead of the typical 10%. Estimate inspection labor for incoming scans, margins, fit, contacts, occlusion, shade, surface finish, labels, and final case release in dental and prosthetics production.

The inputs for this scenario

  • Inspection points or appliances: 120 checks (held at the documented default)
  • Inspection completion pace: 12 checks / hr (held at the documented default)
  • Hold, recheck, and documentation allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base inspection hours = inspection points or appliances รท inspection completion pace.
  • Required quality inspection hours works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base inspection hours works out to 10 hr at these inputs.
  • Hold, recheck, and documentation allowance works out to 7.2 % at these inputs.
  • Inspection completion pace works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where hold, recheck, and documentation allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
  • Use it for daily or shift QC staffing, when projecting headcount for a volume increase, or to justify why inspection is taking longer than raw piece counts suggest. 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 quality inspection hours: 10.72 hr (headline result)
  • Base inspection hours: 10 hr
  • Hold, recheck, and documentation allowance: 7.2 %
  • Inspection completion pace: 12 pieces / min
