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.
One of my favorite definitions of “hacking” is the creative reuse of tools for new and unexpected purposes. Hacking is using your email account as a hard drive, using your bicycle seat to open a beer, using Minecraft’s red bricks to create a calculator in the game.
The opposite of hacking is marketing. Marketing tells you that this particular non-stick pan is the pan you’ll use to make omelettes, and you’ll do it in the morning dressed in fashionable clothing in a nice kitchen. It includes a photo and inspirational copywriting to drive this home. Marketing dictates a style, context, and purpose for even the most general-purpose products. This narrative needs to be specific so that you can readily imagine it: it’s you, in an Airbnb, laughing with friends.
