Descriptions
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.
- Supply Chain Management Registry - The supply chain management registry is responsible for storing and serving inventory reports, consumption reports and shipment notifications. This registry provides visibility into the current inventory levels at each location, their consumption over time and anticipated movements throughout the system.
- 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 warehouses, district and national levels and forecast supply and demand within their catchment area. 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.
