Delivery SLA Attainment at 71% target sla attainment: a worked example

Suppose target sla attainment falls to 71%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate the share of deliveries meeting the committed service level agreement and the gap to the customer or internal SLA target.

The inputs for this scenario

  • Deliveries meeting SLA: 1,150 deliveries (held at the documented default)
  • Total SLA deliveries: 1,200 deliveries (held at the documented default)
  • Target SLA attainment: 71 % (the input this scenario stresses; the baseline uses 98)

Working through the calculation

  • The calculation starts from the formula this tool documents: Delivery SLA Attainment rate = deliveries meeting sla ÷ total sla deliveries × 100.
  • Delivery SLA Attainment rate works out to 95.83 % SLA attainment at these inputs, and this is the headline figure for the scenario.
  • Gap to target works out to -24.83 points at these inputs.
  • Deliveries meeting SLA works out to 1,150 deliveries at these inputs.
  • Total SLA deliveries works out to 1,200 deliveries at these inputs.

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.
  • It computes the delivery SLA attainment rate as deliveries meeting SLA divided by total SLA deliveries, and the point gap to your target. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
