Artifact: Kano Classification — Kestrel Features

Six Kestrel features classified by Kano category -- exercises co-10. Kestrel is a fictional product; every quoted number, question, or finding here is an illustrative, constructed example, not real data or a real transcript.

Feature	Category	Presence-vs-satisfaction shape
No double-booked shifts (scheduling correctness)	Must-be	Absence dissatisfies severely (a double-booking is a real operational failure); presence is simply expected, not delightful.
App uptime / reliability (no crashes)	Must-be	Absence dissatisfies severely; presence is neutral -- nobody praises an app for "not crashing."
Shift-swap approval turnaround time	Performance	Linear: faster turnaround steadily increases satisfaction; slower steadily decreases it.
Mobile push notifications for shift changes	Performance	Linear: more reliable, more timely notifications steadily increase satisfaction; missed or late ones steadily decrease it.
AI auto-schedule suggestions	Attractive	Presence delights (an unexpected, helpful surprise); absence causes no dissatisfaction, since it was never expected.
Confetti animation when a schedule publishes	Attractive	Presence delights briefly; absence is entirely neutral -- nobody expects or misses it.
