The primary audience for the trial run is the Interviewer, who will be talking with customers on Friday. The Interviewer needs to be familiar with the prototype and the sprint questions so he can get the most out of the interviews. (We’ll explain how to run these interviews in the next chapter.) But the whole team will benefit from watching the trial run. If the Decider isn’t a full-time participant in the sprint, now is another good time for a cameo appearance. The Decider can make sure everything matches what she was expecting.
