Inspection Hold Time at 25% disposition and system-update allowance: a worked example

Suppose disposition and system-update allowance falls to 25%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate controlled hold hours caused by required inspection, quality review, or compliance disposition queues.

The inputs for this scenario

  • Lots or records awaiting inspection: 72 items (held at the documented default)
  • Inspections completed per hour: 9 items / hr (held at the documented default)
  • Disposition and system-update allowance: 25 % (the input this scenario stresses; the baseline uses 35)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base inspection queue hours = lots or records awaiting inspection รท inspections completed per hour.
  • Required inspection hold time works out to 10 hr at these inputs, and this is the headline figure for the scenario.
  • Base inspection queue hours works out to 8 hr at these inputs.
  • Disposition and system-update allowance works out to 25 % at these inputs.
  • Inspections completed per hour works out to 9 items / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where disposition and system-update allowance sits at 35% and the headline result is 10.8 hr, this scenario comes in 7.41% below the baseline at 10 hr.
  • It computes the total hours a lot stays on inspection hold by dividing the queue by the inspection rate and adding a disposition and system-update allowance. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Required inspection hold time: 10 hr (headline result)
  • Base inspection queue hours: 8 hr
  • Disposition and system-update allowance: 25 %
  • Inspections completed per hour: 9 items / hr
