Inventory is often discussed as a number of days on hand. That can hide the real engineering question: which uncertainty is the buffer meant to absorb, and where should it sit? For African operations with variable import, transport and supplier lead times, a blanket increase in stock ties up cash while leaving critical items exposed.<\/p>\n

Separate demand from replenishment risk<\/h2>\n

Start with one product family. Record weekly demand, actual order-to-receipt lead times and the causes of delay. A nominal supplier lead time is not the same as the distribution of real arrivals. If a port hand-off, payment release or internal approval adds unpredictable days, the buffer calculation must reflect that variation.<\/p>\n

Set a service target by business consequence. A low-value component that stops an entire production line deserves different treatment from a slow-moving substitute. Use a reorder point built from expected demand during lead time plus a safety allowance for observed variability. Test the result against past stockouts and excess stock, rather than treating a formula as proof.<\/p>\n

Place the buffer where it protects flow<\/h2>\n

More inventory at every site can multiply working capital without improving customer service. Ask whether pooled stock at a regional hub, supplier-held inventory, a second source or a shorter approval path would give better protection. MIT supply-chain research found that supply lead-time variation drove high safety-stock values in two studied products; reducing the underlying variation was a practical lever for lowering buffers.<\/p>\n

This is a systems decision. A local purchasing team rewarded only for unit price may choose large, infrequent orders, while operations absorbs the resulting shortages and storage burden. Make the trade-off visible across procurement, finance, warehousing and customer service. Our earlier supply-chain control-tower guide<\/a> shows how to give those teams one view of exceptions and ownership.<\/p>\n

Run a measured six-week test<\/h2>\n

Choose 20 to 30 items with a mix of criticality and demand patterns. Establish baseline fill rate, stockout days, expediting cost and inventory value. Change one policy at a time, assign an owner for exceptions and review actual arrivals weekly. Compare service and cash together before expanding the policy.<\/p>\n

When the same shortage returns despite higher stock, investigate the feedback loop rather than ordering more. The systems-thinking guide on recurring fixes<\/a> offers a way to trace those unintended consequences. The aim is reliable flow with the smallest justified buffer, supported by better supplier and internal decisions.<\/p>\n
