Method

Five decisions turn uncertainty into a product.

Signal, Proof, Core, Launch, and Scale keep investment tied to evidence instead of speculative surface area.

Every phase ends with a decision, not a ceremony.

Signal
Find the real user pressure, evidence, and business constraint behind the idea.
Exit condition
A specific problem, affected user, and reason to act are agreed.
Proof
Test the riskiest assumptions before product surface area expands.
Exit condition
The core value and highest-risk technical path have credible evidence.
Core
Build the smallest dependable product and its security boundaries.
Exit condition
The critical workflow works end to end with a maintainable architecture.
Launch
Prepare the product, team, and operating feedback loop for real users.
Exit condition
Release, support, observation, and recovery paths are ready.
Scale
Improve the system from operating evidence instead of speculative complexity.
Exit condition
The next constraint is measured and the next investment decision is clear.
