Quarterly Performance for Presort First-Class Mail®
Mailpieces Delivered Between 07/01/2014 and 09/30/2014

Overview

For Presort First-Class Mail®, the service performance measurement system of the 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 the 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 the 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.

 The service performance measures for Single-Piece First-Class Mail® flats (using data from EXFC) serve as proxies for estimating the service performance for Presort First-Class™ flats. The following service performance results combine the results for letter performance calculated by the iMAPS program with the proxy data for flats to measure service performance for all Presort First-Class Mail®.

 Presort First-Class™ Parcels were categorized as a competitive product as of October 3, 2011, and are no longer included in the Presort First-Class Mail® scores.
