Traceability Record Workload at 14% verification and rework allowance: a worked example

Push verification and rework allowance up to 14% and the picture changes. This example computes every intermediate figure at that operating point. Use it when a build adds serialized parts or lot-controlled material and you need to size the hours to record genealogy, material certifications, and as-built traceability.

The inputs for this scenario

  • Serialized or lot-controlled items to record: 150 items (unchanged)
  • Records logged per hour: 20 items / hr (unchanged)
  • Verification and rework allowance: 14 % (raised for this scenario; the documented default is 12)

Working through the calculation

  • Applying the documented formula (Base traceability hours = serialized or lot-controlled items to record รท records logged per hour) to the inputs above produces each figure below.
  • At this operating point the engine returns 8.55 hr for required traceability hours, the number this scenario is built around.
  • At this operating point the engine returns 7.5 hr for base traceability hours.
  • At this operating point the engine returns 14 % for verification and rework allowance applied.
  • At this operating point the engine returns 20 items / hr for records logged per hour.

How this compares with the baseline

  • Against the tool's baseline example, where verification and rework allowance sits at 12% and the headline result is 8.4 hr, this scenario comes in 1.79% above the baseline at 8.55 hr.
  • It computes required traceability hours by dividing the item count by the logging rate and inflating by a verification and rework allowance. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Required traceability hours: 8.55 hr (headline result)
  • Base traceability hours: 7.5 hr
  • Verification and rework allowance applied: 14 %
  • Records logged per hour: 20 items / hr
