The Postal Service takes issue with the audit report’s content, analysis and tone, specifically the inaccurate findings that do not correctly reflect the benefits of Network Rationalization.

The Postal Service agrees with the report’s conclusion that since mail service scores have significantly improved since the operating window change was made in 2015, the Postal Service should not revert back to the prior operating window and implicitly, service standards.

The OIG report’s use of outdated service performance results, combined with a non-statistically valid mailing test may lead to inaccurate conclusions about performance.  In fact, since Network Rationalization was implemented, the Postal Service has not only improved mail service across the country, it has achieved record levels of service across the majority of service categories.
