Quarterly Performance for Presort First-Class Mail®
Service Variance
Mailpieces Delivered Between 07/01/2018 and 09/30/2018

Quarter IV
FY2018

Overview

For Presort First-Class Mail® Letters, Cards, and Flats, the service performance measurement system of U.S. Postal Service® uses documented arrival time at a designated postal facility to start the measurement clock, and an Intelligent Mail® barcode (IMB®) scan by an external, third-party reporter to stop-the-clock. Mail piece tracking from IMB® in-process scans is used in conjunction with the external data to extrapolate results for the population of Presort First-Class Mail® using Full-Service Intelligent Mail®. Data collected by U.S. Postal Service® are provided to an independent, external contractor to calculate service measurement and compile the necessary reports. The system used for this reporting is called the Intelligent Mail® Accuracy and Performance System (iMAPS).

The external contractor determines service performance based on the elapsed time between the start-the-clock event recorded by U.S. Postal Service® and the stop-the-clock event recorded by anonymous households and small businesses that report delivery information directly to the contractor. The service measure consists of two parts: (1) how long mail pieces take to get through processing, and (2) how long mail takes from the last processing scan to delivery. The second portion is used as a delivery factor differential to determine the percent of all Presort First-Class Mail® delivered on the last processing date versus the percent delivered after the last processing date. Service performance is measured by comparing the transit time to USPS® service standards to determine the percent of mail delivered on time.

The Service Performance Measurement (SPM) application of the Full-Service Seamless Acceptance and Service Performance system (SASP) serves as the data source for iMAPS. SPM captures data from all Full-Service Intelligent Mail® and applies business rules for service measurement before sending data to iMAPS.

Service performance measurement was suspended for mail originating from or destined to Caribbean District in FY 2018 Quarter 1 and FY 2018 Quarter 2 due to the devastating impacts of Hurricanes Irma and Maria. Measurement resumed in FY 2018 Quarter 3.
