Review the original question
Return to the learning goal before discussing a new version. Identify which observations answer it and which remain ambiguous. Decide whether the concept should progress, change or be investigated further. Preserve relevant evidence even when the prototype is no longer useful. A series of objects without a decision record can consume time while leaving the same uncertainty intact.
Define the next controlled change
Explain what will change in the next revision and why. Avoid adding several unrelated improvements when one issue needs to be isolated. Assign ownership and link the new work to the current requirements. A completed iteration is more than a finished sample: it is a documented step in the reasoning that makes the next commitment easier to assess.
A practical review checklist
- Revisit the learning goal.
- Record the resulting decision.
- Define the next focused change.
