Supply Chain: Inventory Control & Safety Stock Calculation

Define inventory as raw materials, work in progress, and finished goods, and emphasize turnover as a key kpi driving revenue and earnings, while noting non stock items used internally.

Inventory control supervises supply, storage, and access to maintain adequate yet not excessive stock, guiding planning, ordering, and safety stock to maximize profit and minimize working capital.

Explore how excess inventory buffers demand fluctuations and reveals hidden problems like inaccurate forecasting, while highlighting its carrying costs, space needs, and cash ties in lean manufacturing.

Learn how inventory carrying cost blends landed cost, storage, risk, and capital costs to yield 20%–35% annually, and how these variables drive control strategies and cash flow.

Apply the Pareto principle to classify inventory into A, B, and C by annual value, prioritize A items, and reduce stock through improved forecast accuracy and lead times.

Explore how small order quantities in more frequent orders reduce safety stock and overall inventory. Evaluate splitting the supply approach and its impact on capacity, changeovers, transport, labor, and costs.

Centralize key distribution centers to hold most safety stock, enabling daily replenishments and emergency express deliveries, while evaluating capacity, fulfillment times, and market proximity to determine the optimal dcs mix.

Improve forecast accuracy to reduce safety stock and holding costs, optimize transportation choices, and rebalance supplier proximity and airfreight usage to lower transit stock.

Explore make to stock versus make to order strategies, defined by forecasting and sales orders, where stock is produced ahead or on demand, shaping inventory, safety stock, and lead times.

Explore how make-to-order strategies reduce safety stock by shortening lead times, and how supplier performance management, transparency, and collaboration lower orders, MOQs, and price breaks through beneficial annual commitment agreements.

Cross-docking transfers products from receiving to shipping with minimal handling, enabling direct shipment from supplier to customer and reducing warehousing, storage time, and lead times for a competitive edge.

Apply skew rationalisation to kill underperforming skus using Pareto analysis, then standardize materials to reduce total items, lower safety stock, and free warehouse space for productive inventory.

Adopt a helicopter view to align safety stock across departments, enabling each to focus on its area of influence and reduce total safety stock to about 25% of demand.

Revisit the safety stock paradigm and conclude the topic, then take a brief five-second break to view signboards unrelated to safety stock.
