01 · State the assumptionOpen lesson

A maker considers a product prototype while planning a test. — State the assumption · Original lesson illustration

An idea often depends on several assumptions about demand, willingness to pay, delivery and costs. Identify the most important uncertain assumption first. Make it specific enough to test with a defined group and behavior. Avoid a hypothesis that merely asks whether people like the idea, since agreement can be easier than real commitment.

Worked example

Local parents will book a defined tutoring session at a stated price is more testable than everyone needs this.

Try it yourself

Write one demand hypothesis with a target customer.

What makes an assumption testable?A universal positive statementSpecific people, behavior and conditionsOnly your enthusiasm

02 · Choose a responsible methodOpen lessonLocked — complete previous lessons

A designer gathers feedback on a reusable lunch bag prototype. — Choose a responsible method · Original lesson illustration

Use interviews, prototype feedback or a limited pilot depending on the question. Explain what is real and what is hypothetical, obtain relevant permissions and handle data appropriately. Do not collect payment for an offer you cannot responsibly deliver. The method should test the assumption rather than reward the answer you want.

Worked example

An interview asks how someone currently solves the problem before presenting a proposed solution.

Try it yourself

Choose a method and explain its limits.

What should an interview avoid?Specific questions about current behaviorClarifying an answerLeading questions that invite agreement

03 · Metrics and interpretationOpen lessonLocked — complete previous lessons

Two entrepreneurs review anonymous feedback cards and results. — Metrics and interpretation · Original lesson illustration

Define a useful success criterion before viewing results. Track the denominator as well as the number of positive responses. A small or biased sample has limits. Distinguish interest, sign-up and actual purchase because they represent different levels of commitment. Record negative feedback and alternative explanations instead of deleting inconvenient results.

Worked example

Six sign-ups out of 30 invitations is 20%, not proof that the entire market will buy.

Try it yourself

Calculate a fictional response rate and note a sample limitation.

Why record the denominator?It guarantees a representative sampleIt gives context to the response countIt removes all uncertainty

04 · Decide and reviseOpen lessonLocked — complete previous lessons

Two makers compare an initial fabric pouch with a revised version. — Decide and revise · Original lesson illustration

Compare results with the original criterion and decide whether to continue, revise or stop. A weak result can suggest a change in customer, offer, price or method. Consider costs and operational feasibility alongside demand. Do not keep escalating investment only because you already worked hard on the idea.

Worked example

A pilot finds demand for a narrower service, so the next test changes the scope.

Try it yourself

Complete your test plan and possible next decisions.

What is a useful result of a failed test?Evidence for revising or stopping the planProof that learning was wastedA reason to hide the data

About estimated study time

Lifehelper estimates time from lesson length, worked exercises, practice sessions, project work and assessments. Short foundation courses use approximately two hours; larger courses and multi-level programs use higher estimates. This is not a timer, accredited credit or verified attendance.
