Delivery SLA Attainment at 99% target sla attainment: a worked example

What does the result look like when target sla attainment reaches 99%? The full calculation is worked below with real intermediate numbers. Use it for customer scorecards, carrier reviews, route planning, and service recovery decisions.

The inputs for this scenario

  • Deliveries meeting SLA: 1,150 deliveries (unchanged)
  • Total SLA deliveries: 1,200 deliveries (unchanged)
  • Target SLA attainment: 99 % (raised for this scenario; the documented default is 98)

Working through the calculation

  • Applying the documented formula (Delivery SLA Attainment rate = deliveries meeting sla ÷ total sla deliveries × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 95.83 % SLA attainment for delivery sla attainment rate, the number this scenario is built around.
  • At this operating point the engine returns 3.17 points for gap to target.
  • At this operating point the engine returns 1,150 deliveries for deliveries meeting sla.
  • At this operating point the engine returns 1,200 deliveries for total sla deliveries.

How this compares with the baseline

  • Against the tool's baseline example, where target sla attainment sits at 98% and the headline result is 95.83 % SLA attainment, this scenario lands almost exactly on the baseline at 95.83 % SLA attainment.
  • A figure at this level is achievable when target sla attainment is genuinely sustained, not just peaked for a shift. It measures on-time count only; it does not weight by shipment value, customer tier or how badly a late delivery missed the window.
