Charles Warren from Google talks about the “How Might We?” approach that can lead you through any design challenge:

• Ask “How Might We?” on the goal at hand.
• Open up broader possibilities by asking “Why (should we)?” and gather some answers.
• Pick one and now ask “What stops us?” to focus. That might lead to some interesting answers faster than other approaches…

This combination of questions was devised by Min Basadur, the inventor of simplexity thinking. Look at his site to learn more about Creative Problem Solving (CPS), or ask my friends at StrategicPlay, they can teach you how to use it!
