Incoming Lot Release Time at 29% documentation and disposition allowance: a worked example

Push documentation and disposition allowance up to 29% and the picture changes. This example computes every intermediate figure at that operating point. Use this when planning incoming QC staffing, estimating material lead time impact of inspection holds, or identifying bottlenecks in the receiving process.

The inputs for this scenario

  • Inspection and test points per lot: 20 points (unchanged)
  • Points completed per minute: 0.5 points / min (unchanged)
  • Documentation and disposition allowance: 29 % (raised for this scenario; the documented default is 25)

Working through the calculation

  • Applying the documented formula (Base incoming lot release time = inspection points รท points completed per minute) to the inputs above produces each figure below.
  • At this operating point the engine returns 51.6 min for total lot release time, the number this scenario is built around.
  • At this operating point the engine returns 40 min for base inspection and testing time.
  • At this operating point the engine returns 29 % for documentation and disposition time added.
  • At this operating point the engine returns 0.5 pieces / min for qc processing rate.

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 3.2% above the baseline at 51.6 min.
  • It computes the minutes to release one incoming lot from the number of inspection and test points, the QC throughput rate, and a documentation and disposition allowance. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Total lot release time: 51.6 min (headline result)
  • Base inspection and testing time: 40 min
  • Documentation and disposition time added: 29 %
  • QC processing rate: 0.5 pieces / min
