Write your idea down. SIGMA scores it on the seven things that decide whether it survives, tells you the weakest part, and suggests the cheapest way to prove it.
Polish only blurs the score. Write it as it is.
Problem, solution, revenue, market, differentiation, feasibility, scalability.
Kill, test, or scale — plus the weakest part to fix first.
The cheapest way to prove the weak spot, before you write more code.
A fundamental gap. Rethink the customer, wedge, or distribution.
Promising, but unproven. One cheap experiment comes next.
Strong shape. Earn one paid proof, then push.
