Medical Inspection Time at 14% setup, calibration, and documentation allowance: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop setup, calibration, and documentation allowance to 14%, then walk the calculation through step by step. Estimate total inspection time for a production lot from inspection points, throughput rate, and setup/calibration allowance.

The inputs for this scenario

  • Inspection points per lot: 150 points (held at the documented default)
  • Inspections completed per minute: 2 checks / min (held at the documented default)
  • Setup, calibration, and documentation allowance: 14 % (the input this scenario stresses; the baseline uses 20)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base medical inspection time = inspection points per lot รท inspections completed per minute.
  • Total inspection time (with allowance) works out to 85.5 min at these inputs, and this is the headline figure for the scenario.
  • Base inspection time works out to 75 min at these inputs.
  • Setup and documentation time added works out to 14 % at these inputs.
  • Inspection throughput rate works out to 2 pieces / min at these inputs.

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 5% below the baseline at 85.5 min.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to setup, calibration, and documentation allowance, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. 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): 85.5 min (headline result)
  • Base inspection time: 75 min
  • Setup and documentation time added: 14 %
  • Inspection throughput rate: 2 pieces / min
