Traceability, Serialization & Lot Genealogy worked example

Rework Traceability Load at 7.2% setup, re-linking, and delay allowance: a worked example

This worked example runs the rework traceability load numbers for a tougher week than the baseline: 7.2% setup, re-linking, and delay allowance instead of the typical 10%. Estimate rework traceability load for traceability, serialization and lot genealogy using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.

The inputs for this scenario

  • Reworked units to re-trace: 120 units (held at the documented default)
  • Units re-traced per minute: 12 units / min (held at the documented default)
  • Setup, re-linking, and delay allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base rework traceability load time = rework traceability load workload รท rework traceability load completion rate.
  • Required rework traceability load time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base rework traceability load time works out to 10 hr at these inputs.
  • Rework traceability load allowance applied works out to 7.2 % at these inputs.
  • Rework traceability load completion rate works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where setup, re-linking, and delay allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
  • Use it when rework rates spike, when planning traceability staffing, or when evaluating whether your MES can auto-relink reworked genealogy. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Required rework traceability load time: 10.72 hr (headline result)
  • Base rework traceability load time: 10 hr
  • Rework traceability load allowance applied: 7.2 %
  • Rework traceability load completion rate: 12 pieces / min

Run it with your numbers

  • To rerun this with your own numbers, open the live Rework Traceability Load calculator, set setup, re-linking, and delay allowance to your actual value, and adjust the remaining inputs to match your operation.
