To overcome the difficult situation, IKEA initiated a programmer aimed at taking better control of its supply chain, and enhancing performance in terms of delivery service and costs. A new planning concept was developed and is currently being implemented. Its cornerstones are mutually integrated planning processes, a centralized planning organization, focus on data quality, and use of advanced software support. As a first step in developing the new planning concept, IKEA centralized all forecasting activities and need calculations in order to control stock levels and replenishment throughout the whole supply chain.
