The U.S. Postal Service is consolidating some of its mail processing facilities. Before doing so, USPS must give public notice of the proposed changes and provide information on how the changes will affect costs, employees, and mail service.
But we found that USPS’s process for estimating the costs of these changes doesn’t align with best practices we considered. For example, USPS doesn’t document all the assumptions and methodologies it uses to develop cost estimates. This information would help decision-makers and oversight groups better understand any risks or uncertainty involved in the estimates.
