The USPS has submitted to the PRC an “Informed Visibility (IV) Statistical Design Plan for Internal Service Performance Measurement”.

“The purpose of this document is to describe the proposed statistical design methodology for measuring transit-time performance for various market-dominant product letters and flats. The methodology combines data taken from samples made by Postal personnel with the very large volumes of data available from mail processing to estimate the overall transit-time for mail, and when combined with service standard information allows for the development of estimates of the percent of mail delivered on time and the percent of mail delivered within one day, two days, and three days after the service standard.”
