Welcome to the Operational Services Division's Procurement Information Center. Each major component of the procurement process is presented as a link from this page. The major topic is listed along with associated policy and expanded guidance, some of which have been issued as a separate OSD Policy Guidance documents. We hope you will find this site convenient and user-friendly. We also hope it will be easier for you to keep up-to-date on the latest policy changes. Changes will be accomplished by completely replacing the affected document (which will have a revised date). We will also tell you what has changed.
