Originated by Edward de Bono in his book Serious Creativity, they develop the principle of 'taking one step back' to get a broader perspective.
Widening the Search for SolutionsConcept Fans help you find new approaches
to problem solving, when you have rejected all obvious solutions.

Key points:
The Concept Fan is a useful technique for widening the search for solutions when you have rejected all obvious approaches. It gives you a clear framework within which you can take 'one step back' to get a broader view of a problem.

Key points: (cont.)
To start a concept fan, write the problem in the middle of a piece of paper. Write possible solutions to this problem on lines radiating from this circle.

If no idea is good enough, redefine the problem more broadly: Write this broader definition in a circle to the left of
