Framework · Lean / JTBD

Lean-startup framing around the customer’s job-to-be-done.

Problem-explore (fan) → Problem-pick (waist) → Solution-explore (fan + prototype) → Validate (waist). Anchor on the customer’s job, find the highest-value problem, then validate a minimal solution.

01Best for

When you want to anchor on the customer’s job, find the highest-value problem, then validate a minimal solution.

Shape

Problem-explore → pick → solution-explore → validate.

Best for

Demand-led MVP work anchored on the customer’s job.

Focus

Picks the single highest-value, most-underserved problem first.

Engine

Loops Validate back to Solution-explore until the value prop holds.
