Small details of surprise can add delight to any interface. Consider playful microcopy, a link to a fun video, or the gift of a compliment to a user. The mere discovery of “Easter eggs” such as coupons, virtual gifts, or a humorous image will form a favorable and memorable impression.


According to the Kano model1, delighters are not necessarily expressed in the requirements users are able to express themselves. They are, sometimes small, unexpected, surprises that bring a delightful and fun twist to the user experience. Sometimes they’re unconscious.

Delighters are the happy surprise that can make a difference, and an important source of satisfaction. If delighters aren’t there, dissatisfaction and frustration won’t follow: they’re not expected.

Usually in software development, delighters aren’t a priority, except if it is your product or company strategy. For instance the glass of champagne, when you arrive at the restaurant, the wifi on the plane or in your hotel room, or the mobile touch screen.

In the Kano model, exciters depicted as the keys to Innovation2.
