Validation Methodology

Customer Discovery Script

Opening (2 min)

• Build rapport

• Explain purpose: learning, not selling

Problem Exploration (10 min)

• "Tell me about the last time you dealt with [problem]..."

• "What did you try? What worked/didn't work?"

• "On a scale of 1-10, how painful is this?"

Solution Testing (5 min)

• "If you could wave a magic wand, what would happen?"

• "I'm working on something that [brief description]..."

• "Would this help? Why or why not?"

Commitment Testing (3 min)

• "Would you be interested in trying an early version?"

• "What would you expect to pay for something like this?"

• "Can I follow up when we have something to show?"
