Transit-Time Measurement System

"Measuring USPS service performance since 1990"

IBM (formerly PricewaterhouseCoopers Consulting) has been contracted by the United States Postal Service to conduct an independent, external, Transit-Time Measurement System (TTMS) study. The main goal of TTMS is to measure service performance of the US Postal Service's mail delivery from the customer's point of view.

IBM's National Team of Reporters provide feedback about delivery service by receiving test mail pieces at their homes or small businesses and reporting information about the delivery time. Reporting is easy and convenient. It takes only a few minutes a day to report via our toll free phone number or the internet. Participants receive and respond to test mail which comes with their regular mail delivery and looks just like ordinary mail. If you decide you'd like to be one of our volunteers, here are the steps involved...

IBM will send you some training materials. Read the materials carefully. You will need to be able to receive and collect your mail six days per week (Monday through Saturday) and be willing to report information about the test pieces promptly using a toll free number or website.

When your training is completed, you will start getting test mail. The mail will have no external markings identifying it as test mail as the study is confidential, and we don't want the Postal Service to have any idea you are involved -it's that confidential.
"Even my own family who live in my neighborhood do not know that I am a reporter. Thanks for allowing me to work on your team. It's a pleasure!" - Charlotte, North Carolina

When you open the test mail, each test piece will have a number inside identifying that piece. You will need this number to report the receipt of this mailpiece. You then report receipt of the mailpiece as promptly as possible, using the toll-free call-in number or web site. These reporting methods are available 24 hours a day, 7 days a week.

IBM will be the only contact point. Our volunteers do not know each other, and we do ask you to refrain from telling other people about the program, especially your letter carrier and any local postal employees.

Confidentiality is a critically important component of our mail study and we ask that you do not let your local postal employees know of your participation. Your confidential participation will allow US Postal Service to handle test mail the same as everyday mail so that our scores are truly representative of the service USPS provides to you and your neighbors.

It's simple. We want to test the performance of the mail - a vital part of the overall national fabric - and we want to be sure the study is free from any bias at all. The Postal Service is given daily and weekly updates on the performance of the test mail, and they look for ways to make systemic improvements to improve overall service.

"Thank you for the opportunity to help. The Postal Workers I deal with are so helpful to me, I'm glad to help." - Flint, Michigan

In a very real sense, you would have a role in guiding the Postal Service to help improve it's performance. We know this volunteer effort does take some time, but your involvement will help the United States Postal Service remain one of the premier delivery agents in the world.
