The reason for wanting to use the UCM in this way is to get problem domain experts, that is top management, more involved in systems development by creating a requirements model which can be used by systems developers as a starting point for analysis.

An attempt to measure the creativity of ideas that subjects generated was made in a similar way to how Getzels and Jackson [19] measured creativity in their study of gifted children. The technique has also been tested during a series of case studies which were performed on small businesses. The results of part of one of the case studies are presented as an example of the
