  • The UID strategic imperative has been outlined and reinforced in four consecutive policy memos published since August 2002. USD(AT&L) & USD(COM) memo signed 6 Aug 2002 Subject: Universal Identifier Code PDUAS(AT&L) memo signed 6 Sep 2002 Subject: Universal Identifier Code; Interim Policy PDUSD(AT&L) memo signed 19 Dec 2002 Subject: Forecast of Policy for Unique Identification of Tangible Items PDUSD(AT&L) memo signed 4 Apr 2003 Subject: Forecast of Policy for Unique Identification of Tangible Items - UPDATE These and other related policy documents can be found at www.acq.osd.mil/uid
  • In support of the strategic imperative, DoD established an Integrated Product Team (IPT) to identify the UID data standard and develop an implementation strategy that is both feasible and provides substantial benefit in a reasonable timeframe. The IPT consists of four simultaneous efforts: Standards, Implementation, Policy and DFAR cases. The majority of this presentation will focus on the accomplishments of the Standards effort to date.
  • The Standards Team is comprised of international industry and government experts in asset marking and automatic identification and data capture. The Standards Team has met several times since the Fall of 2002 and come to several agreements regarding: What UID must represent Definitions of key elements of the UID UID Data Content Elements A collaborative solution for following a consistent method for marking and reading the UID With regard to implementation, the Standards Team was not tasked with deciding implementation issues, but rather their charge was to ensure that the UID standard could be implemented before settling on a final policy.
  • The first thing the Standards Team accomplished was to define the UID in plain terms, giving it requirements that must hold up during all aspects of its life.
  • The next accomplishment was to define the terms that make up the UID in order to ensure consistency across international governments and industry. The key terms were designed to be simple and to exist, to the extent possible, in established ISO standards and to avoid imposing new UID-specific requirements.
  • In defining the standards, the team took into consideration that uniqueness needed to be contained within each of the elements that construct the UID. The first element, the enterprise ID, is unique because it is assigned by a registration (or controlling) authority that can be held to a standard of guaranteeing uniqueness. The next elements were more difficult to determine. All enterprises assign serial numbers. However, some enterprises assign serial numbers that are unique within the enterprise and others serialize within parts, or like items. For enterprises that serialize within the enterprise, a simple combination of the enterprise ID and the serial number is sufficient to guarantee uniqueness. For enterprises that serialize within part numbers, the enterprise ID and serial number does not guarantee uniqueness. For enterprises that serialize within part numbers, the original part number must be included in the UID composition in order to guarantee uniqueness. Lastly, an enterprise may mark or label any elements outside the UID-required elements on the part as needed for operational purposes.
  • This chart represents the two UID constructs. Whether an enterprise uses UID Construct #1 or UID Construct #2 depends on whether they serialize items within the enterprise or within part number. The chart also illustrates how to handle rolling part numbers under UID Construct #2 and still guarantee that the UID is permanent over the life of the item. In order to ensure permanence over the life of the item, even if when using UID Construct #2 is used and the part number rolls, the team decided the following: The original part number (assigned at birth) will be used to construct the UID If the part number should roll, the original part number is required to be marked on the item for the entire life of the item in order to reconstruct he UID The current part number may be marked on the item as an additional element
  • This chart represents, under UID Construct #1, the minimum requirements for marking items. The top graphic represents the item marking at birth. The bottom graphic represents the item marking if the part number rolls. Notice that the elements in “A” – the UID elements – would not change, even after the part number changes. It is assumed that enterprise ID and serial number will not change over the life of the item.
  • This chart represents, under UID Construct #2, minimum requirements for marking items. The top graphic represents the item marking at birth. The bottom graphic represents the item marking if the part number rolls. Notice that the elements in “A” – the UID elements – would not change, even after the part number changes. It is assumed that enterprise ID and serial number will not change over the life of the item.
  • This chart shows the relationships between product data, the components of the supply chain, unique items and the UID. An end item may be composed of subassemblies, components and parts. The prime contractor will build to the end item specifications and will pass down these specs, including the UID marking requirements to the tiered vendors for the build of subcontracted subassemblies, components and parts. The end item, as well as all the subassemblies, components and parts will have part numbers assigned in the specs. The various vendors will produce these part-numbered items and deliver them to the prime. Spares may be purchased directly from the vendors or through the prime. These UID-qualifying spare items also have to be marked appropriately with the UID components. So, when the prime delivers the end item, that is one UID. The spares are delivered with their own UIDs. The Government has the option of asking the prime to deliver a list of all UIDs for UID-qualifying items in the end item. The capture of the end item and spares UIDs at time of delivery will satisfy the valuation of assets and inventory and property management requirements.
  • Depending on where you fall on the supply chain, the UID requirement will mean different things. The original implementation goal was to require UID-compliant item markings for all new weapons systems, including major modifications no later than July 2003. Because the July policy memo will be published prior to obtaining ISO approval for the collaborative solution, several questions have been raised about what to do in the interim or what to do if items are marked according to the the collaborative solution and ISO fails to approve it. The policy memo will provide the guidance necessary for government and industry in order to implement UID in the interim.

    6. 6. Key Decisions to Date UID is . . . Data Content Elements Key Terms Collaborative Solution IMPLEMENTATION The IPT Standards effort has agreed to the following elements since the first DoD policy memo was published in August of 2002.
    7. 7. U nique ID entification (UID) is…. UID is . . . . . . the set of data for tangible assets that is globally unique and unambiguous, ensures data integrity and data quality throughout life, and supports multi-faceted business applications and users.
    8. 8. Key Terms <ul><li>Enterprise : Entity responsible for assigning the unique identifier (UID) to a tangible asset. </li></ul><ul><li>Registration (or Controlling) Authority : Organization responsible for assigning a non-repeatable identifier to an enterprise. </li></ul><ul><li>Enterprise Identifier : Code uniquely assigned to an enterprise by a registration (or controlling) authority. </li></ul><ul><li>Serial Number : Code assigned by the enterprise to an item providing for differentiation of that item from any other like or unlike item. Serial numbers can be unique within the enterprise or unique within the part number. </li></ul><ul><li>Part Number : Code assigned by the enterprise to a class of items with the same form, fit, function, and interface. The part number is original if assigned at asset birth and current if reassigned from the original. </li></ul>
    9. 9. Data Content Elements <ul><ul><li>For items that are serialized within the enterprise, the UID is a combination of the enterprise identifier and a serial number that is unique within the enterprise </li></ul></ul><ul><ul><li>For items that are serialized within the part number, the UID is a combination of the the enterprise identifier , the serial number , and the original part number </li></ul></ul>
