The document discusses using the Kano model to measure user delight and inform a UX strategy. It describes the Kano model, which classifies product features into basic expectations, performance features, and excitement generators. A Kano questionnaire is used to evaluate features and determine which category they fall into. The results can show what investments deliver user satisfaction versus delight. The document advocates focusing on basic expectations first before adding delight features, and regularly pruning features to avoid experience rot. Delighters may become basic expectations over time, so continuous innovation is needed.
