Einstein/Noah Bagel uses its data warehouse in real time to maximize cross-selling opportunities. For example, if data warehouse information reveals that a manager in a given store might be missing a cross-selling opportunity on a particular day, an e-mail is automatically sent out to alert managers to the opportunity. Salespeople can then respond by offering the cross-selling opportunity (“How about a cup of hot chocolate with that bagel since it’s so cold outside?”) to the next customer.
