Evaluation of a generic expert system for corporate real estate disposition

Six experts in corporate real-estate disposition contributed their knowledge during five meetings supported by a group support system (GSS). The experts who contributed their knowledge, other experts in disposition, real-estate managers with some disposition experience, and novices evaluated the final version of the resulting expert system prototype, DISPOSITION ADVISOR. One-way ANOVAs revealed that the four groups were significantly different with respect to their disposition experience, their ability to use DOS, their ability to use a spreadsheet, and their level of comfort with using computers. Groups also ran the system for a significantly different number of properties, and they provided significantly different ratings for the clarity of DISPOSITION ADVISOR´s messages to the user, their satisfaction with the sequence in which questions are asked, and how flexible the system is in allowing the user to make use of various features.<>
