Requirements are grouped into which three categories according to Kano?

The correct categorization of requirements according to Kano’s Model is into standard/base, performance, and excitement categories. This model helps in understanding user satisfaction in relation to different types of requirements and features.

Standard/base requirements represent the fundamental expectations users have. These are the minimum features that must be satisfied for users to consider a product acceptable. For example, a car must have basic functionalities such as wheels and an engine; without these, customer satisfaction drops significantly.

Performance requirements are those that users explicitly desire and whose fulfillment can increase satisfaction. These are often directly related to how well the product performs or the level of quality it offers. For instance, a car’s speed and fuel efficiency fall into this category because improvements can lead to higher customer satisfaction.

Excitement requirements are the unexpected features that can delight users but are not necessarily expected. They offer a sense of enjoyment and can significantly enhance customer loyalty when present. An example might be a car that has advanced technology like autonomous driving capabilities, which surprises and impresses users.

The other choices present different frameworks that do not align with the nuances of the Kano Model. Understanding these distinctions can help teams prioritize features and better address user needs.
