The Amazon Project

This project is to monitor what percentage of on-time deliveries Amazon achieves on my orders for home & work* in 2022. I was motivated when Amazon started shifting Prime deliveries to my home & work between various distribution centers, and the delivery issues seemed to have taken a huge jump up. Ironically, they often pass the final destination going to the final distribution center further away than the 2nd to last Amazon facility.

An on-time delivery is when Amazon delivers all items in a given order on or before the date promised at the time the order is placed. If an item was lost in transit ("Never Delivered") and Amazon automatically reordered it, that reorder appears as a separate order in the list and is held to the new order's original promised delivery date. If I do this next year, I will add a "days late" column.

As of the last update on November 21, 2022, Amazon's on-time delivery rate on my orders was approximately 90.1%. This is quite a bit lower than what Statista reports for Amazon's on-time delivery rate. I'll also point out that from monitoring Amazon's order fulfillment, the main reason for Amazon's missing delivery dates is waiting until the last minute to ship. In other words, most 2-day shipments don't seem to start the fulfillment process until the day before the promised delivery date.

* An attempted delivery on or before the promise date but when the business is closed counts as an on-time delivery.

If Amazon changed the promise date after the order is submitted, the original promise date at the time of order submission is used as that original promise date is, like price, part of the bargain they proposed to entice me to submit the order.
