When to use it
Use it when a design, set of instructions or game can be represented safely with inexpensive materials before the finished version is made.
How to use it
Choose one question the trial can answer. For example, ask whether a new user can identify the starting card without your explanation. Put unrelated design questions on a later list.
Build only the pieces needed to examine that question. Use paper, cardboard or another suitable low-cost model. Confirm permission, safe materials and a clear place to work before involving other people.
Invite a willing tester and explain the activity without revealing the answer you are trying to test. Observe their ordinary choices; do not continually correct them into using the model as you imagined.
Record specific behavior and the tester’s own explanation. Distinguish a pause you observed from why you think it occurred. Ask what the person noticed or expected rather than supplying your intended meaning.
Choose one meaningful change, make another version and try it again. Keep enough of the first version and notes to compare. If circumstances differ between attempts, include that difference in the record.
Write a limited conclusion and the next question. A few successful trials with individuals do not prove that every visitor or a crowd will manage the finished system. Save remaining confusion as information.
A worked example
A practical illustration of the method.
A club tests three picture labels using clean paper cards. One visitor mistakes a shaded carton for a partly full container. Instead of explaining the intended picture and marking the test successful, the maker records the confusion, simplifies the drawing and adds a short label. A later trial is clearer, but a hand still hides another sign. The playbook records progress on picture clarity and a separate unresolved placement question.
Use it thoughtfully
Do not coach the tester through every difficulty and then conclude the design was self-explanatory.
Do not spend the whole session making the model impressive before testing the central question.
A revision that helps one person is useful evidence, not a universal effectiveness claim.
From the book
A simple record that helps you build a rough model, test one question, and improve the idea using what you learn.
