Why Better Isn’t Always Better: Noriaki Kano’s Theory of Satisfaction

Why does a feature that once amazed us eventually become something we simply expect?

Noriaki Kano’s Kano Model offers a fascinating explanation. In his work on Attractive Quality and Must-Be Quality, Kano showed that not all product and service attributes influence satisfaction in the same way. Some are basic expectations. Some generate satisfaction as performance improves. And some create delight precisely because we never expected them.

But the most interesting part is what happens next: today’s innovation can become tomorrow’s expectation.

In this episode, we explore the Kano Model and connect it to customer experience, innovation, product strategy, psychology, personal development, leadership, AI, and the way human expectations constantly evolve.

Why do we stop noticing things that once felt extraordinary? Why can adding more features actually make a product worse? Why can’t customers always tell us what the next great innovation should be? And what does all of this have to teach us about our own lives and expectations?

From smartphones and customer experience to personal growth and artificial intelligence, the Kano Model reveals a powerful idea:

What is extraordinary today may become invisible tomorrow.

And perhaps the real challenge isn't simply creating better things. It is understanding what people expect, what they value, and what they don't even know they could want.
