Intuition will always play a role in all phases of new product development. Obviously more on the fuzzy front, but not eliminated in downstream activities like pricing studies either.
Imo, the more experience you have, the more trust you will have in your intuition. Yes, it may be more intrinsic in some than others, but I think it correlates well to how many times you fell off that pony.
You can get all the quant data you want, but at some point you have to pull the trigger, tear the Band-Aid, just do it or whatever cliché is appropriate. Nothing is without intuition.
