Question
What are the three parts of the development cycle?
Answer
Model — build the cheapest thing that answers the current question. Test — with real users, measuring something. Refine — change the design because of what happened. Then repeat.
Question
Why does fidelity rise across the loops?
Answer
Because the questions get harder. Reach can be answered with card at the right height; stability needs real weight and real materials.
Question
Why change one thing per loop?
Answer
So an improvement can be attributed to a known change. Two changes at once hide which one worked, and can hide one making things worse.
Question
When does development stop?
Answer
When every essential criterion has been measured and met — not at the deadline and not when the model looks finished. Criteria not yet met are recorded honestly.
