Kano Analysis, an important tool for product development, uses a structured methodology to help determine important device characteristics. For example, if customers expect a device will have a certain feature, they would be disappointed if it isn't there. However, if it were there, it doesn't create satisfaction; it was assumed.
If the device has a very nice feature, it will please users. They are happy to have it, but probably wouldn't be disappointed if it were not included.
Kano Analysis provides the method to classify these device aspects using a pair of questions about each device characteristic for the classification. The questions are for potential or current users and the resulting analysis determines the category.
This technique allows you to include the essential aspects, the customer expectations, into your device as well as some characteristics that help increase satisfaction. The technique also helps with design validation, because it can identify patient or user needs. You can also use the information to develop design inputs and their corresponding essential design outputs.
