Prototyping and Playtesting: Turn Each Version into One Answerable Question
Technical terms: Iterative prototyping, Playtesting, Individual prototype, Accumulative prototype
Iterative prototyping builds the cheapest playable form that can test a design question, observes what happens, revises, and repeats. Playtesting is structured observation of people using that form.
An individual prototype is a disposable experiment for one risky idea. An accumulative prototype is a growing foundation into which validated pieces are integrated. The first favors fast learning; the second reveals interaction and moves toward production.
See it in Same Circles
A paper circle and movable letters can test whether people enjoy intersecting words: an individual prototype. A stable browser editor that gradually receives validated creation and sharing features is accumulative.
What you can do with it
Write the question before building. Observe behavior as well as opinion; players often report their feelings accurately while guessing incorrectly about the cause.
Ask a player
What did you try to do, what did you expect to happen, and where did the experience differ?
Nearby ideas
- Experience goal — state what the prototype is meant to produce.
- User-centered design — observe actual people in context.
- System tuning — adjust relationships after the structure exists.
- Design hypothesis — make an assumption explicit and testable.
