Product features can be divided into three categories
First, the threshold function, a required function
The bed in the hotel, the bathroom table, the cleanliness of the room, etc. are threshold functions However, improving threshold functionality, or increasing, has little impact on customer satisfaction
Second, linear function, the more the better
The bed in the hotel, of course, the bigger the better (you know); the cleaner the room of course, the more comfortable it is The more these linear features manifest as much as possible, the happier the customer will be
Third, the excitement
Xiaobian found that some hotels actually have elliptical trainers and bicycle fitness machines, and some executive suites have a small swimming pool, wow, simply beautiful edgeless, next time must return, the high price also feels worth it Conversely, I wouldn't be dissatisfied if most of the hotel rooms didn't have these devices available So, the excitement is those features that offer high satisfaction and can often add an extra price to the product. But the lack of excitement doesn't make customers unhappy, and in fact excitement can also be mapped to unenvirted needs, even when users don't know what they need until they see them
Since we understand that the product functions are divided into three categories, how many necessary functions and how many linear functions are needed in each function delivered to the customer, see the diagram
The curve in the upper left shows that even if only one excitement or surprise point is achieved, customer satisfaction will increase significantly; since the product must have the necessary functions to survive in the market, the threshold function should be emphasized, and users should regard these functions as mandatory, so the product should be made available before the release, but as long as it is partially implemented, it is enough
The second focus is to complete as many online features as possible, because each of these features directly leads to higher customer satisfaction, of course, the more the better
Finally, if time permits, at least a small number of excitement points should be prioritized and included in the release plan
It's also important to remember that features move down in the kano model. For example, the wifi wireless network was still an exciting point many years ago, and now it is a linear function, and it is converting to the threshold function. do you see clearly?
