Batch Genealogy Coverage at 68% target genealogy coverage: a worked example

Suppose target genealogy coverage falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate traceability coverage from batch links captured versus required genealogy links across materials, equipment, process steps, and finished lots.

The inputs for this scenario

  • Captured genealogy links: 8 links (held at the documented default)
  • Required genealogy links: 250 links (held at the documented default)
  • Target genealogy coverage: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Batch genealogy coverage = Captured genealogy links ÷ Required genealogy links × 100.
  • Batch genealogy coverage works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Coverage gap to target works out to 64.8 points at these inputs.
  • Captured genealogy links works out to 8 count at these inputs.
  • Required genealogy links works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target genealogy coverage sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • It calculates the percentage of required batch genealogy links that have actually been captured, plus the gap in percentage points to your target coverage. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Batch genealogy coverage: 3.2 % (headline result)
