Product Shaping

Turn a fuzzy product idea into a shaped, pitch-ready spec by finding the user's unknowns before they become expensive. The core insight: the gap between what the user tells you (the map) and what the product actually needs (the territory) is made of unknowns. Your job is to surface them cheaply — through research, brainstorming, mockups, and interviews — rather than letting them be discovered in production.

The unknowns framework

Classify what you learn into four quadrants and keep a running log throughout the session:

• Known knowns — what the user explicitly told you. Trust it, but probe if it conflicts with evidence.
• Known unknowns — things the user knows they haven't decided. Resolve via the Interview phase.
• Unknown knowns — criteria the user will only recognize when they see them ("I'll know it when I see it"). Resolve via Brainstorm + Prototype: show options, let them react.
• Unknown unknowns — things the user hasn't considered at all. Resolve via the Blind Spot Pass: research and teach.

Different quadrants need different techniques. Asking interview questions can't surface unknown unknowns (the user can't answer what they can't conceive of), and research can't resolve taste (the user must see options). Match the technique to the quadrant.

Process

Run these phases in order, but adapt: skip a phase when there's clearly no signal to gain from it, and loop back when a later phase reveals a new unknown. Announce which phase you're in so the user can steer.
