Assumption Mapping & Risk Reduction

Identify what must be true for your idea to succeed, map those assumptions by importance and evidence, then run the smallest tests that can break the risky ones first. You will use a simple 2x2 assumption map, learn falsification thinking, and build a short risk plan that feeds your next steps. This module sets you up for later work on bets and experiments without going deep into experimentation math.

Context and why it matters in 2026

Identify what must be true for your idea to succeed, map those assumptions by importance and evidence, then run the smallest tests that can break the risky ones first. You will use a simple 2x2 assumption map, learn falsification thinking, and build a short risk plan that feeds your next steps. This module sets you up for later work on bets and experiments without going deep into experimentation math.

In modern product teams, progress depends on clear playbooks and measurable outcomes. This module gives you practical steps you can apply immediately while keeping alignment with the broader Product Discovery curriculum.
