Lot Genealogy Completeness at 35% record completeness gap: a worked example

What does the result look like when record completeness gap reaches 35%? The full calculation is worked below with real intermediate numbers. A traceability engineer uses it to budget the effort to remediate incomplete lot linkage ahead of an audit or recall readiness review.

The inputs for this scenario

  • Production lots to reconstruct: 300 lots (unchanged)
  • Cost per lot reconstruction: 40 $/lot (unchanged)
  • Record completeness gap: 35 % (raised for this scenario; the documented default is 30)
  • System and audit adder: 2,500 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Genealogy gap cost = lots x cost per lot x completeness gap% + system adder) to the inputs above produces each figure below.
  • At this operating point the engine returns 6,700 $ for total lot genealogy completeness cost, the number this scenario is built around.
  • At this operating point the engine returns 22.33 $ / piece for lot genealogy completeness cost per unit.
  • At this operating point the engine returns 4,200 $ for variable lot genealogy completeness cost.
  • At this operating point the engine returns 2,500 $ for fixed lot genealogy completeness adder.

How this compares with the baseline

  • Against the tool's baseline example, where record completeness gap sits at 30% and the headline result is 6,100 $, this scenario comes in 9.84% above the baseline at 6,700 $.
  • A figure at this level is achievable when record completeness gap is genuinely sustained, not just peaked for a shift. It assumes a uniform per-lot reconstruction cost — deeply broken lots requiring supplier data pulls cost far more than the average implies.
