Kano

Kano is a model used in product development and customer satisfaction to understand how different features impact user satisfaction. It categorizes features into five types: basic needs (expected but unremarkable), performance needs (directly improve satisfaction when enhanced), excitement needs (delight users unexpectedly), indifferent factors (no impact), and reverse needs (may annoy if present). The goal is to prioritize features that balance essential functions with innovative or exciting elements, ultimately creating products that meet basic expectations while exceeding user delight and fostering loyalty.
