"A sense of possibility ... imagines something that might be possible but has not been considered possible or even potentially possible so far. (... sense of
possibility is often used synonymously with imagination even though imagination is not the same as sense of possibility, for imagination also encapsulates the impossible)." (Dörner, D., & Funke, J.

Today's world is becoming more and more complex, there is a multitude of new insights and a greater understanding of how different developments affect each other. This great complexity requires systematic thinking in order to identify new opportunities and threats as problems.
"Problems in the sense of the SE [Systems Engineering] mainly express themselves in a discomfort, a more or less well-founded criticism of an unsatisfactory situation, in the representation of a possible opportunity or an impending danger and the related questions. ... The problem can be formulated in a relatively concrete manner, or it may merely consist of vague assumptions about problems and their causes." (Daenzer, W. F.
