Out of the Gijs van Wulfen’s “20 Tips for Ideation Excellence” I especially likes #7:
7. Great ideas for innovative new products or services fit 7 criteria. Use them actively in your project: 1. Very appealing to customers. 2. It stands out in the market. 3. It has great potential for extra turnover. 4. It has adequate profit potential. 5. It fits management’s personal goals. 6. It is (somehow) considered quickly feasible. 7. It creates its own internal support.
