Based on the number of subsystems reached by tracing the relationship from each requirement item. In addition, for each of the request items of the plurality of request items, the result display unit (140) identifies the group in which the request item is classified, the number of subsystems reached by tracing the relationship from the request item, and The analysis result information (30) for which is set is displayed.
