Supplier on‑time delivery directly affects line readiness, overtime, and customer service. Many plants treat it as a leading indicator for schedule adherence. A one‑day slip on a critical component can cascade into missed build slots and expedite fees. Tracking the rate each week or month helps separate normal variation from sustained drift that needs action.
Use a written definition that matches your receiving process. Common rules include delivery on or before the requested date, within an agreed window such as ±1 day, or within a time-of-day cutoff for dock appointments. Keep exceptions consistent: partial shipments, supplier‑caused carrier delays, and customer‑driven reschedules should be classified the same way every period.
A single target like 95% is useful, but performance varies by lane and part family. Segment results by commodity, plant, and supplier tier to find where risk concentrates. High‑volume suppliers should be reviewed with tighter statistical tolerance, while low‑volume suppliers may need rolling periods to stabilize the denominator. Use the gap to target to prioritize corrective actions. Also compare performance month over month to the supplier’s lead time and carrier mode, because premium freight can hide chronic planning issues.
Point-in-time results can look healthy while trends deteriorate. Logging each period allows you to chart three to eight data points, identify seasonality, and confirm whether containment actions worked. After a corrective action, look for sustained improvement over at least two reporting cycles, not a single rebound week. Add brief notes so audits can trace decisions to evidence.
In supplier reviews, pair the on‑time rate with late counts and top delay reasons. Share a simple action plan: owner, due date, and verification method. When the rate falls below target, escalate using clear thresholds, for example a two‑period miss or a large late count on critical parts. Export the log to share with stakeholders and support quarterly scorecards. For mature programs, combine this metric with defect ppm and responsiveness to build a balanced supplier risk index for sourcing decisions.
Use the rule your receiving team can verify: on or before requested date, within an agreed window, or within a dock appointment cutoff. Document exceptions and apply them consistently.
Decide whether the delivery is counted by purchase order line, shipment, or receipt. If completeness matters, treat incomplete deliveries as late or create a separate “complete and on‑time” metric.
Start with historical performance and business impact. Many programs set 90–98% depending on lead time, variability, and criticality. Tighten targets for high‑risk parts or strategic suppliers.
The metric may ignore early deliveries, quantity short, or schedule changes. Review late counts on critical parts, compare to promised lead times, and add notes on reschedules and shortages.
Weekly reporting reacts faster but can be noisy at low volume. Monthly smooths variation. Use the log to keep both views: weekly for containment, monthly for scorecards.
