This section contains a textual description of each item added to the diagram above:

• Product Registry -

  The product registry is responsible for standardizing and serving a list of commodities and items that are available within the system. At minimum, it provides a list of available commodities that are available for distribution, consumption and disbursement within the system. In more advanced cases, the product registry is able to serve detailed information on each item that is available within the system including lot and serial number information collected as GTIN and SGTINs. The information in the product registry supports numerous transactions in the health, supply chain and reporting workflows

  A Product Registry serves as the source of truth about what a Product is within an HIE.  It sources the information for this role through two expected means:  1) as the ongoing result of a process of master data management to properly define and categorize medical products and 2) as derived data on the proper definition and categorization of medical products (e.g. GS1 GDSN).

• Logistics Management Information System (LMIS) - The LMIS is responsible for storing and serving inventory reports, consumption reports and shipment notifications. This provides visibility into the current inventory levels at each location, their usage over time, anticipated movements throughout the system and is a key system in supply chain decision support.
• Warehouse Management System (WMS) - The warehouse management system is a point of service system that is used at large warehouses to track the products that are available for order, pick, pack and shipping. WMS are different from inventory control systems because they handle much larger product volumes than expected at the end nodes in the system.
• Enterprise Resource Planning (ERP) System - The enterprise resource planning system is a point of service system that is responsible for planning the supply chain needs over a period of time. ERP systems often operate at large national or sub-national warehouses where they help in managing the business functions of these larger warehouses.  ERP systems are often linked with WMS at large warehouses. ERPs systems often have a financial tracking component (purchase orders, accounts receivable/payable, financial accounts and ledgers).
• Inventory Control System - The inventory control system is a point of service system that is run at the location where commodities are dispensed to the patient populations. These systems often function within a dispensary, keep track of the individual transactions and support compiling inventory reports and consumption reports. These systems are often the final destination for commodities before they are distributed to the patient. 
• Shipping/Third Party Logisticians (3PL) - Third party logistics companies is a catch all term for point of service organizations that are responsible for transporting commodities between points in the supply chain. These operators receive notification of a shipment that needs to be picked up, they arrange the transportation, pick the shipment and deliver it the the appropriate place. The recipient is often responsible for verifying the shipment once received A Logistics Management Information System (LMIS) is an IT system that plays a central role in enabling commodity visibility and operational management of a wide-area supply chain operation.  Typically the commodities in this supply chain are health-related, the organization that sponsors the system is a department or agency under a government's health ministry and the operation is carried out at scale for an entire region or even an entire nation. An LMIS typically bridges the health and supply chain operations by enabling re-supply workflows for clinical locations and the vertical programs targeting families of commodities, as well as interfacing with supplier's IT systems to ensure the re-supply process is fulfilled as needed.  Particular LMIS tools may have additional capabilities that enhance these re-supply workflows and/or add to the maturity of the wider supply chain operation.

Functional Architecture

The functional architecture focuses on identifying the functions required in the supply chain as well as the workflows that deliver those functions.
