Plan one useful
customer test.

Move from “I think this could work” to a question you can investigate.

Prepare customer questions, make sense of observations and put a bounded test plan together. Five lessons, worked examples and a final applied task.

Who it is for

An idea you want to examine.

For someone considering a business idea or a change to an existing service. You do not need a finished business plan, research participants or a purchase to work through the lessons.

What you will make

A test you can explain.

A short plan connecting a decision, a question, an activity, a record of evidence and a review point. You can prepare it before running a test.

You mark lessons reviewed yourself. Practice feedback helps you reflect; it does not award a qualification or establish that a business idea is proven.

The learning sequence

Build the plan one piece at a time.

  1. 01

    Choose a question worth answering.

    Write one question that names a situation, something you can observe and a decision the answer would inform.

    Available
  2. 02

    Ask about a real experience.

    Write a question about a recent relevant experience and a follow-up that does not suggest the answer.

    Available
  3. 03

    Separate observation and interpretation.

    Distinguish an observed action or quotation from an interpretation, and write a plausible alternative explanation.

    Available
  4. 04

    Design a small test.

    Describe a bounded activity, the observations it will produce and a point at which you will stop and review.

    Available
  5. 05

    Review evidence and decide the next step.

    Write a proportionate next step, identify what remains unknown and state what would lead you to revisit the decision.

    Available
  6. ↳

    Your test plan.

    Bring your notes together, check the connections and keep a copy.

    Applied task

How you will learn

Read. Try. Reflect.

Each lesson has an explanation, a fictional worked example, a practice question with feedback and space to apply it. You can read in order or revisit any lesson. Marking a lesson reviewed is separate from merely visiting it.

Use it in your work

The tools stay close.

Your course notes stay together in this course. Existing worksheets open separately, with a return to the lesson; answers are not transferred automatically.
