One thing that I took with me from the speech is that:
“user’s need are verbs and not nouns”
Let me explain that: when you have to understand people’s needs, because you have to design something to service them, ask them to describe the need as a verb.
So I don’t need a STAIR (noun), a stair is a already a solution, “I need to go up (verb) to …” .
I give you an extra tip for free 🙂 : the most the description of the need is ‘open’ (= less constraints, more general), the highes is the number of innovative options you can get back.
p.s. Thank you Matteo for teaching me that 🙂
