Topics result from the review of the ideas, the correspondent problems and the derived goals. The goals can be derived from the problems by looking at certain aspects (context, relations, net, associations, pro/con and ecology). Based on the problem net core problems, causes and effects are described, to transfer them into a goal net. Goal net consists of the major goal and the supporting sub-goals as well as the expected effects.
The compiled sketches are still no concepts. However, that way, ideas are already substantially more concrete and goals are defined in a first version. The core elements of the concept can already be identified. These concept alternatives are compiled in the next step - Draft.
