Once the proposal evaluation strategy has been developed and purchase planning completed, the RFP is issued. Publicizing purchasing opportunities (including RFPs and prequalification opportunities) includes the process of publicly announcing an RFP. Purchasing opportunities are publicized to create, promote and ensure adequate competition. Publication enhances the potential for innovative proposals and product offerings. In addition, publicizing purchase opportunities supports Postal Service objectives of promoting SMWOB participation in Postal Service requirements.
