  • Patent number: 7613281
    Abstract: A processing system allows for the monitoring of user requests such that a response may be provided within a defined maximum processing time (MPT). The user request relating to issues or concerns with a product or application/usage of the product is received through an input portal, such as a web site. The user request is assigned a response time, typically based on the type of request, where the response time indicates a preferred guideline for how quickly an assistant should provide a response. Once the request has been assigned to an assistant, a notification is generated to inform the assistant about the user request and the corresponding deadline for response. At a pre-determined time prior to the expiration of the response time, it is determined if the response has been provided. If the response has not been provided, a reminder is generated to inform the assistant of the pending deadline.
