How can you measure the potential success of a design before you’ve spent millions building the final product? This episode explores "NPSX" (Experiential Net Promoter Score), a powerful leading indicator that tests the emotional resonance of early prototypes. By asking customers to rate their experience during the "Humility" phase of the Pulse, teams gain a "prescient" look at their future market performance. Learn how to use this metric to justify design investments and ensure your team is always building toward a high-value outcome.
