New mandates on how evaluation criteria must be stated in Postal Service solicitations are required by the recently revised USPS Supplying Principles and Practices (SPP) manual. The SPP revisions were issued on December 12, 2011. The full text of the new SPP is available by clicking here. In addition to these changes, the Postal Service has introduced a new “Simplified Purchasing” method. Simplified Purchasing will be more streamlined than the traditional method, will commonly use oral solicitations, and may be used on procurements valued at up to $1 million.
