Different supply chain strategies exist to meet the varying demands of products and markets. Lean strategies focus on reducing waste and non-value activities to improve efficiency. Agile strategies emphasize flexibility and speed to respond rapidly to changing customer demands. Postponement strategies delay final manufacturing until receipt of a customer order to minimize risks of incorrect inventory. Speculation strategies seek savings through bulk manufacturing and distribution to reduce costs. The key is selecting the strategy best suited to a company's specific product attributes, customer requirements, and market characteristics.
