In the two years that we have existed, and with quite a bit of experience, we have found that coming up with good, innovative solutions to a problem is not the most difficult part of our work at all ...

A good problem definition is clear and specific, offers solutions for a actually experienced problem, which it is likely to be solved in an innovative way. For this we developed the Challenge Canvas (with download!)
