Component Attrition at 1% target component attrition: a worked example

This worked example runs the component attrition numbers for a tougher week than the baseline: 1% target component attrition instead of the typical 0.4%. Measure component attrition percentage from lost, scrapped, or consumed extra parts versus total issued parts.

The inputs for this scenario

  • Attrited or lost components: 640 components (held at the documented default)
  • Total components issued: 185,000 components (held at the documented default)
  • Target component attrition: 1 % (the input this scenario stresses; the baseline uses 0.4)

Working through the calculation

  • The calculation starts from the formula this tool documents: Component attrition rate = attrited or lost components รท total components issued.
  • Component attrition rate works out to 0.35 % attrition at these inputs, and this is the headline figure for the scenario.
  • Attrition gap to target works out to 0.65 points at these inputs.
  • Attrited components works out to 640 components at these inputs.
  • Total components issued works out to 185,000 components at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target component attrition sits at 0.4% and the headline result is 0.35 % attrition, this scenario lands almost exactly on the baseline at 0.35 % attrition.
  • Use it when setting kitting overage factors, reconciling line returns against issued quantity, or auditing a feeder or machine that seems to chew through parts. 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

  • Component attrition rate: 0.35 % attrition (headline result)
  • Attrition gap to target: 0.65 points
  • Attrited components: 640 components
  • Total components issued: 185,000 components
