Once you see that an answer is not serving its question properly anymore, it should be tossed away. It's just their natural life cycle.
They usually kick and scream, raising one hell of a ruckus when we ask them to leave. Especially when they have been with us for a long time.
You see, too many actions have been based on those answers. Too much work and energy invested on them. They feel so important, so full of themselves. They will answer to no one. Not even to their initial question!
The hardest thing about customer interviews is knowing where to dig. An effective interview is more like a friendly interrogation. We don’t want to learn what customers think about the product, or what they like or dislike — we want to know what happened and how they chose... To get those answers we can’t just ask surface questions, we have to keep digging back behind the answers to find out what really happened.
Normally after the design was built, you would find places for the art to be located and then you would go out and select the artist that you wanted. That is historically, the traditional way to go.
But this time, someone else was calling the shots. A planning official, basically, who comes along and says, “We want you guys to work with an artist.” And the architects are like, “Sure of course.” But then the official goes—“No, you don’t quite understand. We want you to use an artist as a co-equal member of the design team.” That is, the artists are going to have just as much control as the architects. It was really unheard of.
