Requirements for successful application of a demand-driven supply network include demand synchronization between stakeholders. This ensures that all parties involved, such as suppliers, manufacturers, and retailers, are aligned and can respond to changes in demand efficiently and effectively. This synchronization is crucial for reducing lead times, minimizing inventory levels, and improving customer service. While automatic communication of data from POS terminals and jointly determined safety stock can also contribute to the efficiency of the supply chain, they are part of the broader concept of synchronization.
