The Smallest Version Worth Testing
Building the whole thing before anyone has paid for it is the standard way to waste a year. The useful question is what is the least you could put in front of a real customer that would still teach you something.
What a learner can do afterwards
- Reduce an idea to the smallest version that still tests the risky assumption
- Name the one assumption whose failure would kill the whole idea, and design the test for it
- Explain why a test that cannot fail teaches nothing

Building the whole thing before anyone has paid for it is the standard way to waste a year. The useful question is smaller: what is the least you could put in front of a real customer that still teaches you something? Pick one customer, one painful problem, and one simple offer. Early sales teach what people actually pay for, which often differs from what they praise in conversation.
You think busy parents will buy prepped dinner boxes. Instead of renting a kitchen, you cook ten boxes at home, sell them by hand to parents at one school gate, and watch what happens. If they rebuy, demand is real. If they praise but never pay, you learned cheaply what a full launch would have taught expensively.
Aim every early test at the one assumption whose failure kills the whole idea, usually that nobody wants the product. A first plan fits on one page: customer, problem, offer, cost, and how money arrives. If any box stays vague, that vagueness is your riskiest assumption, and your next test should attack it. Test demand without building: presell, offer the service yourself, or run a manual concierge version behind a simple page.
Design the failure in, or the test teaches nothing. Decide in advance what result would prove you wrong, and fall in love with the problem rather than your solution, so evidence can change your mind. After each loop, update the plan with what you learned and name the next test and its cost. Revenue from tiny tests then buys each next step, and fixed costs stay near zero so experiments are cheap to kill.
Shrink the idea to one risky test, run it by hand, and listen to the result.
