Inventory Management is the discipline of ordering, storing, tracking and controlling the stock of goods, components and materials an organisation holds across its supply chain. It seeks to balance the cost of holding stock against the risk of stock-outs, using forecasting, reorder policies and real-time visibility of quantities and locations. Modern implementations integrate barcodes, RFID and digital identifiers so that physical items can be reconciled against system records continuously.
Overview
- Inventory management spans raw materials, work-in-progress and finished goods. It applies policies such as economic order quantity, just-in-time replenishment and safety-stock buffers to decide what to hold, where and when to reorder. Effective practice depends on accurate data: every receipt, issue, transfer and adjustment must be recorded so that the system view matches the physical warehouse.
Key aspects
- Stock control — tracking quantities on hand, allocated and available across locations.
- Reorder policy — reorder points, lot sizing and safety stock to prevent stock-outs.
- Demand forecasting — projecting future consumption to drive replenishment.
- Cycle counting and audit — periodic reconciliation of physical stock to records.
- Identification — barcodes, RFID tags and serial numbers for item-level tracking.
Applications
- Retail and e-commerce order fulfilment.
- Manufacturing component and raw-material control.
- Healthcare consumables and pharmaceutical stock.
- Spare-parts and maintenance, repair and operations (MRO) inventories.
