Rapid Prototyping

Comment l'animer

1. 1

   Define what assumption you're testing before you start. A prototype without a learning goal is just a model.

2. 2

   Choose the lowest-fidelity format that can test your assumption: paper sketch, cardboard model, role-play script, clickable mock-up.

3. 3

   Build it. Timebox strictly (20-45 min). Ugly is fine — it's not the point.

4. 4

   Test with a real user or stakeholder. Show, don't explain. Watch what they do, not just what they say.

5. 5

   Capture observations: what confused them? What worked? What surprised you?

6. 6

   Decide: iterate (tweak the prototype and test again), pivot (fundamentally change the idea), or proceed (build it).

Conseils

• The fidelity of your prototype should match your confidence level. Low confidence = paper. High confidence = high-fidelity.

• Don't explain the prototype during testing. If they don't understand it, that's data.

• Multiple rough prototypes beat one polished one — test more ideas, faster.

• Use role-play to prototype services and conversations, not just products.

Variantes

Wizard of Oz prototype: simulate functionality manually behind the scenes while users interact with a front-end. Powerful for testing AI/automated features.Storyboard prototype: draw a comic-strip sequence showing how a user would experience the solution.
