KJ method, which was developed for creative thinking, uses cards for m
aking a conceptual map from brainstorming. A card-handling editor for
supporting the method is presented and was used for analysing requirem
ents of software. The most important effect of using the editor is tha
t not only the relations between the brainstormed matters but also wha
t is lacking in them can be found. The editor is found to be a very us
eful tool for recording the creative thinking process, and can be used
afterwards for interpreting the specification which is a result of th
e requirement analysis. (C) 1997 Elsevier Science B.V.
