It's SO important to ask questions that give you measurable data. Ask your interviewees to tell you a story about the last time they had ___problem x___ (or) ask them what the ideal solution is for ___problem x___. As Cindy Alvarez has put it: "Almost anyone will do anything for you as long as: the request is short, you are enthusiastic, and they don't have to make any decision that requires more than one minute of thought." Knowing this, why ask yes/no questions when you can get more from your interviewees.
Great post. Though Lean terminology doesn't jive with the meaning of "valid" and "truth" that I learned in my logic class. Shouldn't we be testing our hypotheses for "truth" rather than "validity"?
I got out of the building this past weekend in New York. I know first hand that you have to ask the right questions of the right potential buyer to get useful information.
The planning right before heading out to talk to people is super super important - nice post
super insightful. What happened to the Byoyo team after the workshop?
