When a prototype kills an experiment
The win is not always ship. Sometimes the prototype surfaces the objection that should have killed the idea before a sprint was spent.
Tomas Laurinavicius
A credible prototype changes the meeting even when the answer is no. The team can reject a specific interaction, a specific claim, or a specific placement instead of rejecting a foggy bullet.
That is still success for a growth manager. Cheap death beats expensive ambiguity.
