Have you ever used task and requirement prioritization methods (MoSCoW, Kano model)?

Yes, I used both requirement prioritization methods.

MoSCoW categorizes requirements into: Must have, Should have, Could have, Won't have. This helps focus on critical features when resources are limited.

Kano Model classifies requirements based on their impact on user satisfaction: basic, expected, attractive. It helps identify which features will bring the most value and improve user experience.

Example of application: during release planning, I first identified Must have requirements using MoSCoW, then analyzed them with the Kano model to understand which ones would truly increase customer satisfaction.
