Turn your Lean Canvas into a testable model

Problem & customer segments

Write the three most important problems and the specific early adopters who experience them. List current alternatives. Link claims to customer evidence.

Value proposition & solution

Describe the outcome the customer wants, then the smallest solution that delivers it. Avoid a list of features without a clear customer benefit.

Channels, revenue & costs

Explain how you reach customers, who pays and how often, and what it costs to serve them. Treat untested prices and channels as assumptions.

Key metrics & unfair advantage

Choose metrics that reveal repeat value, not just attention. An unfair advantage must be hard to buy or copy. Label hoped-for advantages as hypotheses.

Make the connections explicit

Check whether your chosen customer can be reached through your proposed channel, whether the payer receives enough value to justify the price, and whether the delivery cost allows a viable contribution. A coherent canvas explains these relationships instead of treating its boxes as independent answers.

Review it as a team

1. Mark each claim as supported, partly supported, or untested.
2. Link the strongest available evidence and its limitations.
3. Choose the assumption whose failure would most change the model.
4. Design the next test and assign an owner.
5. Save a new version when the evidence changes a meaningful choice.

Do not fill every box with confident language just to make the canvas look complete. An explicit uncertainty is more useful than an unsupported answer. Connect pricing and cost assumptions to your unit economics.
