In order to institutionalize supply chain management throughout the Postal
Service™, these Supplying Principles and Practices have been developed to
replace the Interim Internal Purchasing Guidelines. The Supplying Practices
are intended for internal use only to assist the Postal Service in obtaining
best value and efficiently conducting its supply chain functions. They are
advisory and illustrative of approaches that may generally be used by Postal
Service employees to conduct SCM activities, but are intended to provide for
flexibility and discretion in their application to specific business situations.
They are designed to supplement the Postal Service's purchasing regulations
contained in 39 C.F.R. Part 601.
The Supplying Principles are the overarching business principles which the
Postal Service will follow in its SCM efforts. The Supplying Practices are the
business practices the Postal Service will follow to fulfill the intent of the
Principles. The Practices are organized according to six process steps and
those process steps are further organized according to tasks and topics.
While the process steps and tasks are organized sequentially, some practices
are sometimes carried out simultaneously, and others may not be applicable
to a specific business situation. The Purchase/SCM Team is responsible for
selecting the Supplying Practices that are applicable or relevant to a specific
In addition to the specific Supplying Practices organized by Process Steps,
Tasks and Topics, there are General Supplying Practices which inform the
entire supply chain process, and Commodity-Specific Practices. The General
Practices address overarching topics and include subjects such as Laws, and
Material and Property Accountability. The Commodity-Specific Practices
discuss business practices relevant to a specific commodity such as mail
transportation or design and construction.
The Vice President (VP), Supply Management (SM), is responsible for
ensuring that Postal Service supplying activities further the business and
competitive interests of the Postal Service and for approving and issuing the
Supplying Principles and Practices, and supplemental guidance. Proposed
changes to enhance the Supplying Principles and Practices are welcome
from all supply chain stakeholders, including suppliers and the general public.
