Abstract: A system and method for customer satisfaction survey for a customer service provided over a telephone network. A customer initiates a telephone call to a customer service number provided by a company. The company's PBX receives the call and transfers it to a computer telephony integration (CTI) server for dynamically assigning an available customer service representative to the call. During the course of a call, the CTI server monitors the call for push-tones transmitted by the caller. Receipt of a push-tone during the conversation is assumed to be an indication of the customer's satisfaction associated with the call at the time the push-tone was transmitted. The CTI server also presents questions to the customer at the end of the call but prior to hangup to receive additional feedback about the customer's satisfaction about the call. The gathered information is stored as customer satisfaction data for later analysis by an analysis computer.

Abstract: A system and method for continuously monitoring and updating delivery schedules based on completed deliveries and customer modifications. A delivery scheduling computer stores and updates delivery schedule information, notifying the customer prior to a scheduled delivery of an estimated time of delivery. The notification is made to a customer's PC, browser-based client, hand-held computer or set-top box, or by conventional communication methods such as a telephone, pager, or cellular phone. If the customer desires to change the time or location of the delivery, the customer transmits a delivery change request and the schedule is modified accordingly. Employees use a hand-held computer or a browser-based client to receive updated delivery schedule information, as well as to transmit a delivery completion message to the delivery scheduling computer. The message includes an actual delivery time which the delivery scheduling computer uses to update the estimated delivery times of the remaining deliveries.
