Kaizen Inventory Management

Inventory management refers to the process of management of inventory or finished goods within the organization. It is a very simple concept that says, ‘don’t have too much inventory and don’t have too little’. The need to inventory management arises due to various factors, including Capacity constraints, Quality issues, Layout, Big batches & High changeover time, Minimum order quantity, Ordering & replenishment system, High demand variation due to seasonality or more. And, since significant extra cost may be involved in straying goods above and below the optimal range, careful inventory management can make a huge difference in the profitability of a business.

Inventories are generally produced and stored according to the current demand and supply expectations of the market and any excess in inventories weakens business competitiveness by increasing operating costs & decreasing the margins. Therefore, it is crucial to have the right balance of inventory in the organization and the managers must keep a check on it.
