Worked example

Inputs

Inspected
1000 units
Opportunities
4 opportunities/unit
Defects
20 defects
Defective units
15 units

Expected results

Dpmo
5000 defects/million opportunities
Defective share
1.5 %
Defects per unit
0.02 defects/unit

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

{
  "inspected": 1000,
  "opportunities": 4,
  "defects": 20,
  "defective_units": 15
}

Accuracy and scope

Each opportunity can have at most one recorded defect; does not convert DPMO to a sigma level or establish sampling confidence.
