State the learning goal
Decide whether the prototype is exploring appearance, fit, interaction or another defined requirement. Write down what the team wants to observe and which aspects of the prototype are intentionally different from the intended product. A model made for a visual review should not quietly become evidence of structural performance. The value lies in the question it can answer reliably.
Choose the next step from the result
Record the observations before discussing the next iteration. Distinguish a flaw in the concept from a limitation of the prototype’s construction. If a result is uncertain, explain what additional work would resolve it. Do not keep polishing an object that cannot test the intended question. A small purposeful prototype can guide a decision more effectively than an impressive sample with no clear evaluation plan.
A practical review checklist
- Define one learning goal.
- Label prototype limitations.
- Record observations before conclusions.
