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.
The CYCLE OF GOODNESS® is the corporate philosophy established by YKK’s founder, Tadao Yoshida, who believed that “no one prospers without rendering benefit to others.” It expresses the basic belief of the YKK Group. Tadao Yoshida firmly believed that business belongs to society. As an important member of society, a company survives through coexistence. When the benefits are shared, the value of the company’s existence will be recognized by society. When pursuing his business, Mr. Yoshida was most concerned with that aspect and would find a path leading to mutual prosperity. He believed that using ingenuity and inventiveness in business activities and constantly creating new value would lead to the success of clients and business partners and make it possible to contribute to society. This type of reasoning is referred to as the CYCLE OF GOODNESS® and has always served as the foundation of our business activities.
