Incoming Lot Release Time at 18% documentation and disposition allowance: a worked example

This worked example runs the incoming lot release time numbers for a tougher week than the baseline: 18% documentation and disposition allowance instead of the typical 25%. Estimate time to complete incoming material/component lot release including inspection, testing, and documentation.

The inputs for this scenario

  • Inspection and test points per lot: 20 points (held at the documented default)
  • Points completed per minute: 0.5 points / min (held at the documented default)
  • Documentation and disposition allowance: 18 % (the input this scenario stresses; the baseline uses 25)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base incoming lot release time = inspection points รท points completed per minute.
  • Total lot release time works out to 47.2 min at these inputs, and this is the headline figure for the scenario.
  • Base inspection and testing time works out to 40 min at these inputs.
  • Documentation and disposition time added works out to 18 % at these inputs.
  • QC processing rate works out to 0.5 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where documentation and disposition allowance sits at 25% and the headline result is 50 min, this scenario comes in 5.6% below the baseline at 47.2 min.
  • Use it when planning incoming inspection capacity, setting dock-to-stock lead time, or balancing inspection headcount against receiving volume. 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

  • Total lot release time: 47.2 min (headline result)
  • Base inspection and testing time: 40 min
  • Documentation and disposition time added: 18 %
  • QC processing rate: 0.5 pieces / min
