Reshoring & Tariff Strategy worked example

Regional Sourcing Service Level at 61% application efficiency: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop application efficiency to 61%, then walk the calculation through step by step. Estimate regional sourcing service level for reshoring and tariff strategy using production-ready inputs so teams can size the purchase quantity or material requirement without relying on a rough guess.

The inputs for this scenario

  • Regional sourcing service level area or quantity: 500 units (held at the documented default)
  • Regional sourcing service level use per unit: 0.08 units / unit (held at the documented default)
  • Application efficiency: 61 % (the input this scenario stresses; the baseline uses 85)

Working through the calculation

  • The calculation starts from the formula this tool documents: Theoretical regional sourcing service level amount = regional sourcing service level area or quantity × regional sourcing service level use per unit.
  • Required regional sourcing service level quantity works out to 65.57 units at these inputs, and this is the headline figure for the scenario.
  • Theoretical regional sourcing service level amount works out to 40 units at these inputs.
  • Regional sourcing service level loss allowance works out to 25.57 units at these inputs.
  • Application efficiency works out to 61 % at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where application efficiency sits at 85% and the headline result is 47.06 units, this scenario comes in 39.34% above the baseline at 65.57 units.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to application efficiency, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a single fixed efficiency figure, so it will mis-size orders if efficiency varies by batch, season, or operator.

Results at a glance

  • Required regional sourcing service level quantity: 65.57 units (headline result)
  • Theoretical regional sourcing service level amount: 40 units
  • Regional sourcing service level loss allowance: 25.57 units
  • Application efficiency: 61 %
