Abstract
A system and method for supporting an interactive decision tree with placeholder capability include an interactive decision tree-based expert unit with an input enabled to receive user data that includes a user identification and with an output enabled to transmit system data. A memory is connected to the expert unit for storing the system data. Optionally, the user memory stores the identification and an associated decision tree node identifier representing a node in the decision tree visited by a user prior to termination of a communications link between the expert unit and the user. A device is provided for accessing the decision tree node identifier from the memory utilizing the associated user identification, so that a connecting device can automatically connect the user to a node within the decision tree based solely upon the user identification. Alternatively, the decision tree node identifier is transmitted to the user. Upon reconnecting to the expert unit, the user transmits the node identifier to the expert unit to reconnect to the decision tree at the node represented by the node identifier.
