Supplier Quality, Development & Audits worked example

Incoming Inspection Burden at 7.2% setup, handling, and delay allowance: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop setup, handling, and delay allowance to 7.2%, then walk the calculation through step by step. Estimate incoming inspection burden for supplier quality, development and audits using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.

The inputs for this scenario

  • Parts to inspect on receipt: 120 units (held at the documented default)
  • Inspection throughput per inspector: 12 units / min (held at the documented default)
  • Setup, handling, and delay 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 incoming inspection burden time = incoming inspection burden workload รท incoming inspection burden completion rate.
  • Required incoming inspection burden time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base incoming inspection burden time works out to 10 hr at these inputs.
  • Incoming inspection burden allowance applied works out to 7.2 % at these inputs.
  • Incoming inspection burden completion rate works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where setup, handling, and delay allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to setup, handling, and delay allowance, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a steady throughput rate; complex first-article, layout, or destructive checks with variable cycle times will exceed the linear estimate.

Results at a glance

  • Required incoming inspection burden time: 10.72 hr (headline result)
  • Base incoming inspection burden time: 10 hr
  • Incoming inspection burden allowance applied: 7.2 %
  • Incoming inspection burden completion rate: 12 pieces / min
