All manual-based processes are prone to human error. Even a conceivably simple task, such as picking a product off a warehouse shelf to match a customer order, can be fouled up by a human being. Just ask Coca-Cola Enterprises, Inc. (CCE). This bottler and distributor of Coke products experienced a marked decline in customer order accuracy as a result of human error in the warehouse picking process. CCE implemented a VoIP-based voice-activated picking solution to improve its order accuracy, streamline its picking processes, and increase employee productivity.
