The goal of lean inventory, a tactic based on lean manufacturing principles, is to reduce waste while maintaining product availability. The objective is to support Just-in-Time (JIT) inventory models by maintaining only the necessary amount of inventory at the appropriate time and location. Agile procedures, precise demand forecasting, and solid supplier relationships are necessary for implementing lean inventory practices. It improves cash flow and lowers carrying costs, but it also necessitates strong risk mitigation to handle supply interruptions or abrupt shifts in demand.
