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.

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.
Most organizations use some version of an innovation funnel to bring ideas to life. It starts with lots of ideas at the front end and then launches whatever survives all the way to the back end.
