Research Question

A research question can be simple , however shouldn't it be able to sustain research for a lifetime for the more passionnate?
It should also tackle Innovation.
What is Innovation?
I've been reading so much lately about the word innovation, being innovative , "good design is good business" etc..
Can we really be innovative and is it really about innovation? Design is always walking side to side with Innovation , its nearly as though both terms can't live without each other.
My question is how much design out there is really an Innovation?
