Operations

ETA

Estimated Time of Arrival. The single most-checked field in any delivery operation. Quality of an ETA is a function of how live the data underneath it is.

Where this fits

The day-to-day vocabulary of running deliveries. Routes, waves, drops, manifests, ETAs, SLAs. These are the units operators reason in, and the inputs every downstream model needs.

Related terms

POD: Proof of Delivery. The artifact (photo, signature, geolocation, notes) captured at the doorstep that proves the drop happened. Increasingly verified by AI rather than by human review.
SLA: Service-Level Agreement. The contracted performance threshold: on-time rate, delivery window, refund triggers. The thing operators are graded against.
Drop: A single delivery completion. The driver hands the package off and POD closes the order. Most last-mile teams measure first-attempt drop rate, the share of orders successfully delivered on the first try.
Cross-dock: A facility where inbound freight is unloaded and reloaded onto outbound vehicles directly, without sitting in storage. Used to consolidate or reshuffle loads in transit.
Manifest: The driver's load list for a route: what's on the truck, in what order, going where. The source of truth for a tour.
