The service center obtains (202) customer information pertaining to the customer and identifies (204) from the customer information one or more customer-related keywords from a selection of predefined keywords. The service center then selects (206) a set of option nodes from the default tree structure based on a mapping of the one or more identified customer-related keywords to keywords assigned to the option nodes, and creates (208)a customized tree structure comprising the selected set of option nodes. The service center is then able to assist (210) the customer to navigate through a reduced succession of choice options in accordance with the customized tree structure, thus providing a more efficient and user-friendly experience to the customer. |
