I just discovered JPD today, so forgive me if this is a noob question.
It strikes me that JPD is very idea-centric, instead of outcome / goal / problem - centric. I would like to see strong support for modern product discovery methodologies like those found in SVPG's Inspired or Product Talk's Continuous Discovery Habits.
I think most companies have a deluge of ideas, often lacking strong linkage to a problem that is clearly worth solving. I want to get out of the feature factory mentality, and looking for tools that support this instead of adding fuel to the ideas bonfire :-)
