Double Diamond
It's often used in design. The Double Diamond helps separate moments of idea exploration from moments of focus and decision-making.
Motivational Interviewing
This one is all about building motivation in individuals, rather than just sharing knowledge or plans. Sometimes people have conflicting desires and reasons for change. I recommend you follow the course "Motivational Interviewing - Foundational" from Psychwire to learn the basics of this approach. It's an affordable online course by the founders of the approach.
