Inspection Fixture Workload at 8.64% load, record, and review allowance: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop load, record, and review allowance to 8.64%, then walk the calculation through step by step. Estimate inspection labor hours for loading, locating, clamping, measuring, unloading, and recording results from inspection fixtures.

The inputs for this scenario

  • Parts inspected on the fixture: 480 parts (held at the documented default)
  • Fixture inspection throughput: 55 parts / hr (held at the documented default)
  • Load, record, and review allowance: 8.64 % (the input this scenario stresses; the baseline uses 12)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base inspection fixture workload time = parts inspected with fixture ÷ inspection-fixture throughput.
  • Required inspection fixture workload time works out to 9.48 hr at these inputs, and this is the headline figure for the scenario.
  • Base inspection fixture workload time works out to 8.73 hr at these inputs.
  • Loading, recording, and review allowance works out to 8.64 % at these inputs.
  • Inspection-fixture throughput works out to 55 parts / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where load, record, and review allowance sits at 12% and the headline result is 9.77 hr, this scenario comes in 3% below the baseline at 9.48 hr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to load, record, and review allowance, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. The single allowance percentage lumps together loading, recording, and review — if any one of those swings widely between part numbers, split the calculation per part family rather than trusting one blended figure.

Results at a glance

  • Required inspection fixture workload time: 9.48 hr (headline result)
  • Base inspection fixture workload time: 8.73 hr
  • Loading, recording, and review allowance: 8.64 %
  • Inspection-fixture throughput: 55 parts / hr
