Supplier On-Time Delivery at 71% target otd: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target otd to 71%, then walk the calculation through step by step. Calculate on-time delivery for Supply Chain & Procurement: on-time deliveries as a share of total deliveries.

The inputs for this scenario

On-time deliveries: 188 deliveries (held at the documented default)
Total deliveries: 200 deliveries (held at the documented default)
Target OTD: 71 % (the input this scenario stresses; the baseline uses 98)

Working through the calculation

The calculation starts from the formula this tool documents: On-time delivery = on-time deliveries ÷ total deliveries × 100.
On-time delivery works out to 94 % at these inputs, and this is the headline figure for the scenario.
Gap to target works out to -23 points at these inputs.
On-time deliveries works out to 188 count at these inputs.
Total deliveries works out to 200 count at these inputs.

How this compares with the baseline

Against the tool's baseline example, where target otd sits at 98% and the headline result is 94 %, this scenario lands almost exactly on the baseline at 94 %.
The practical read: the gap between this scenario and the baseline is entirely attributable to target otd, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It treats every delivery equally, so a single late drop of a critical line-down part counts the same as a late shipment of low-value consumables; weight by impact for sourcing decisions.
