Component Attrition at 0.46% target component attrition: a worked example

Push target component attrition up to 0.46% and the picture changes. This example computes every intermediate figure at that operating point. a materials planner is checking whether component attrition is eroding kit accuracy or quote margin

The inputs for this scenario

  • Attrited or lost components: 640 components (unchanged)
  • Total components issued: 185,000 components (unchanged)
  • Target component attrition: 0.46 % (raised for this scenario; the documented default is 0.4)

Working through the calculation

  • Applying the documented formula (Component attrition rate = attrited or lost components รท total components issued) to the inputs above produces each figure below.
  • At this operating point the engine returns 0.35 % attrition for component attrition rate, the number this scenario is built around.
  • At this operating point the engine returns 0.11 points for attrition gap to target.
  • At this operating point the engine returns 640 components for attrited components.
  • At this operating point the engine returns 185,000 components for total components issued.

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.
  • It computes the percentage of issued components lost to attrition and the gap between that rate and your planning target. 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

  • Component attrition rate: 0.35 % attrition (headline result)
  • Attrition gap to target: 0.11 points
  • Attrited components: 640 components
  • Total components issued: 185,000 components
