Who is the protagonist?
Purpose: Why do they do what they do? What drives them?
Function: What is the mechanism behind this?
Form: What could it look like?
If you’re looking to understand your subject from a developmental standpoint, another way of framing this is with the Japanese philosophy of Ikigai:
1) What are they passionate about?
What hobbies or interests do they have? What gives them energy just thinking about it?
2) What skills or talent underpins that passion?
Is there a particular element of their passion or interest they like the most or that comes most naturally?
3) What issues in the world do they care about?
What matters to them? What do they think a better world looks like?
4) How can they use those skills to address those issues?
Is there a mission or career that allows them to take their skills and apply it to making the world a better place?
