Made for real tasks

Worked example

Inputs

Units

Second detection
75 %

Expected results

Initial defects
200 units
Escapes
10 units

Load the example in the workspace to reproduce these results. Display rounding does not change the underlying calculation.

How to use this tool

  1. Enter the measured quantities and planning assumptions in the displayed units.
  2. Run the calculation, then compare the result with your available capacity or actual records.
  3. Change one assumption at a time to compare operating scenarios.

Try this example

{
  "units": 10000,
  "defect_rate": 2,
  "first_detection": 80,
  "second_detection": 75
}

Accuracy and scope

Second detection rate applies to defects missed by the first gate; no independence assumption about equal unconditional rates.
