Medical Inspection Time at 23% setup, calibration, and documentation allowance: a worked example

What does the result look like when setup, calibration, and documentation allowance reaches 23%? The full calculation is worked below with real intermediate numbers. Use this when scheduling inspection operations, estimating QC staffing needs, or identifying inspection bottlenecks in production flow.

The inputs for this scenario

  • Inspection points per lot: 150 points (unchanged)
  • Inspections completed per minute: 2 checks / min (unchanged)
  • Setup, calibration, and documentation allowance: 23 % (raised for this scenario; the documented default is 20)

Working through the calculation

  • Applying the documented formula (Base medical inspection time = inspection points per lot รท inspections completed per minute) to the inputs above produces each figure below.
  • At this operating point the engine returns 92.25 min for total inspection time (with allowance), the number this scenario is built around.
  • At this operating point the engine returns 75 min for base inspection time.
  • At this operating point the engine returns 23 % for setup and documentation time added.
  • At this operating point the engine returns 2 pieces / min for inspection throughput rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup, calibration, and documentation allowance sits at 20% and the headline result is 90 min, this scenario comes in 2.5% above the baseline at 92.25 min.
  • A figure at this level is achievable when setup, calibration, and documentation allowance is genuinely sustained, not just peaked for a shift. It models a steady inspection rate; lots with mixed inspection types, frequent gauge changes, or high reject-and-recheck rates can run longer than a single average rate predicts.

Results at a glance

  • Total inspection time (with allowance): 92.25 min (headline result)
  • Base inspection time: 75 min
  • Setup and documentation time added: 23 %
  • Inspection throughput rate: 2 pieces / min
