How Might We (HMW)

Reframe problems as opportunities.

Problem: Users abandon signup
HMW: How might we make signup feel rewarding?
HMW: How might we reduce signup friction?
HMW: How might we show value before signup?

Idea Evaluation

After brainstorming, evaluate ideas:

Diverge → Converge

1. Diverge: Generate many ideas (no filter)
2. Organize: Group similar ideas
3. Converge: Select best ideas to pursue
