How do I evaluate customer discovery interview evidence for bias?

Evaluating customer discovery interview evidence involves analyzing an evidence log across five dimensions to identify confirmation bias, leading questions, and signal quality. This process assigns an Evidence Quality Score to determine readiness for advancing to Lean Canvas routing.

What is an Evidence Quality Score in customer discovery?

An Evidence Quality Score is a composite metric generated by adversarially auditing interview evidence. It assesses confirmation bias, leading questions, signal versus noise, willingness-to-pay signals, and pattern recognition to produce actionable feedback for Stage 3 readiness.

How do I check willingness-to-pay signals from customer interviews?

Checking willingness-to-pay signals requires auditing your interview evidence log for concrete monetary intent. The evaluation extracts specific quotes and assesses their strength to produce a structured breakdown of viable monetization data.

When do I need an evidence review before creating a Lean Canvas?
