The preeminent design firm IDEO works from three key strategies for creativity: diversity, empathy and prototyping. Diversity of perspectives enriches the possibilities to consider. Empathetic undertanding of users drives practicality of approaches. Prototyping accelerates experimenting and learning that's critical to any new efforts.
These are the opposites of endless discussing, speculation and assumptions. They should be core to any innovation process in business, education and community transformation.
