Design Sprint Test and Score (Friday)

Friday is the sprint's payoff. 5 target-profile customers run the prototype while the team observes; the team synthesizes observations into a scorecard against the sprint questions; the Decider makes the build / iterate / pivot / stop call by end-of-day. The week's 35-40 person-days plus customer recruiting cost converts into one actionable decision.
