Abstract: A customer support management system and method resolves both hardware and software problems using a single business model. The system and method is based on interaction between a hierarchy of corporate personnel/consultants and a customer support management system which tracks the evolution of customer support requests from inception to completion. The customer support management system includes a number of software tools including an automated scheduler connected to a database system for storing at least one of customer, product, service provider, and routing information. When a customer experiences a problem with a hardware or software product, the customer sends a support request to the manufacturer. Through an interactive process, first, between the manufacturer and the customer and, then, between system personnel, the system tools are utilized to locate a service provider anywhere in the world in order to provide on-site support for satisfying the customer support request.
