# Kano Model

Classify product features into categories based on how their presence or absence affects user satisfaction, guiding prioritization decisions.

## Steps

1. **List candidate features** — Gather all features or improvements under consideration.
2. **Design Kano questionnaire** — For each feature, ask two questions: "How would you feel if this feature were present?" and "How would you feel if it were absent?"
3. **Collect responses** — Survey target users using the functional/dysfunctional question pairs.
4. **Classify each feature** — Map responses to categories: Must-be (expected baseline), Performance (more is better), Delighter (unexpected wow), Indifferent, or Reverse.
5. **Prioritize** — Ensure all Must-be features are covered first, then invest in Performance features, and add Delighters for differentiation.

## Output Format

A table with columns: Feature, Category (Must-be / Performance / Delighter / Indifferent / Reverse), Evidence, and Priority recommendation.
