Abstract

A system construction assistance apparatus includes a first display screen, a second display screen, and a processing section displaying units each belonging to one of categories on the first display screen such that the units are sorted by category, receiving a first input to select one unit from the units displayed on the first display screen, generating a system configuration diagram on the basis of the received first input, and displaying the generated system configuration diagram on the second display screen. After a first input is newly received and before a next first input is received, the processing section predicts a category to which a unit to be selected by the next first input belongs on the basis of first inputs received in a past and presents the predicted category as a candidate category to a user.
