Can you explain each opportunity (Accurate "Pull" Data and Lot Size Reduction) and give real-life situations/examples of each?

Pull data Accurate sales data that initiate transactions to pull product through the supply chain Opportunities in Managing the Integrated Supply Chain Opportunities for effective management in the supply chain include the following 10 items. Accurate "Pull" Data Accurate pull data are generated by sharing (1) point-of-sales (POS) information so that each member of the chain can schedule effectively and (2) computer-assisted ordering (CAO). This implies using POS systems that collect sales data and then adjusting that data for market factors, inventory on hand, and outstanding orders. Then a net order is sent directly to the supplier, who is responsible for maintaining the finished-goods inventory. Lot Size Reduction Lot sizes are reduced through aggressive management. This may in- clude (1) developing economical shipments of less than truckload lots; (2) providing discounts based on total annual volume rather than size of individual shipments; and (3) reducing the cost of ordering through techniques such as standing orders and various forms of electronic purchasing
