Validation is a sequence of decisions
A credible business idea is not the one with the most enthusiastic description. It is the one whose riskiest assumptions have been exposed to evidence. Customer interviews are useful when they examine recent behavior, present workarounds and actual commitments rather than asking whether somebody likes a hypothetical product.
Use the lowest score to choose the next experiment
Do not average away a fatal weakness. A product with attractive demand but impossible acquisition economics is still a weak business. Select the lowest-scoring domain, state what evidence would change your decision and run the smallest ethical test that can produce that evidence.
- Write the assumption in a falsifiable sentence.
- Choose evidence stronger than stated intention.
- Set the pass, revise and stop thresholds in advance.
- Limit the time and money committed to the test.
- Record contradictory evidence instead of explaining it away.

What does a business idea validator measure?
This tool organizes six evidence domains: customer observation, problem intensity, alternatives, economics, distribution and experiment quality. It does not predict startup success.
Should I build a minimum viable product before validation?
Not necessarily. Interviews, observed workflows, smoke tests, letters of intent and manually delivered prototypes can test critical assumptions before software or inventory is built.
Does MTF Institute receive my answers?
No. The calculation runs locally in your browser and the answers are not submitted to MTF Institute or stored by this tool.
