Procedure 3201 PR.01 Purchase Order Process

This substantially revised/reimagined procedure is proposed by Procurement (the policy sponsor). Formerly named Purchase Requisition Process, this procedure has been renamed and revised to better capture the end-to-end process related to purchase orders (POs). This procedure now documents the comprehensive set of PO practices and establishes a baseline for correctly executing POs and managing the PO lifecycle.

  • This revised procedure is designed to, among other things:
  • Establish definitions and best practices around POs;
  • Assist the University community in correctly executing POs;
  • Clarify roles and responsibilities throughout the PO lifecycle;
  • Improve adherence to Yale’s purchasing policies and procedures; and
  • Reduce re-work, audit issues, and fraud incidents for PO usage.

By implementing the revisions to this procedure, the intent is to improve the end-user experience by:

  • Clarifying the current PO processes for experienced and new users;
  • Having a one-stop reference for preparing, creating, and managing a PO;
  • Improving understanding of why and when a PO is needed;
  • Eliminating re-work, saving time, and ensuring the timely receipt of purchases; and
  • Establishing the foundation for future trainings.

The document also received non-substantive, clarifying revisions to enhance clarity and consistency with related documents.

There will be a significant change management and training effort related to this document. Additional information on those efforts will be forthcoming.
