Why this matters
Craft compounds when it is attached to judgment. Product thinking is the practice of deciding what deserves to exist, what to leave out, and how a product earns a place in someone's life.
Concepts to learn
- Product theses
- User evidence
- Activation and return
- Scope and refusal
- Business and operating model
Apply It in Casset
Casset is the working environment for this skill—not the curriculum itself.
- Write the bet behind one Profile World or Casset App before changing the surface.
- Use product data and observation to decide what should be removed, clarified, or made canonical.
- Record one refusal: what Casset should not become while solving the current problem.
Suggested project
Decision journal
A series of short records connecting product evidence to a concrete choice.
Evidence of completion
These are completion conditions, not claimed achievements. Each stays planned until it links to a real artifact or verification.

- observationA user observation that changes the thesisplanned
- analyticsA decision supported or challenged by product evidenceplanned
Open questions
- What evidence is enough to change a strong point of view?
- How can a refusal remain useful as the product evolves?
