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.
Design means something even broader now. Sometime around World War II, it came to mean making things that “solve problems.” With the influence of mid-century global social movements and the rise of digital technology, it began to mean making things that are “human-centered.” And as of recently, design doesn’t have to involve making things at all. It can just mean a way of thinking.
Of all these developments, the idea of design as a broadly applicable way of thinking—the idea of “design thinking”—may end up being the most influential…At Stanford’s d.school, as cofounder Robert Sutton has said, “design thinking” is often treated “more like a religion than a set of practices for sparking creativity.”
