CORE DEFINITION

A five-dimensional metric system for quantifying user experience: Happiness, Engagement, Adoption, Retention, and Task Success.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Data-driven experience: solves the problem of 'whether the experience is good or not depends entirely on the boss's feeling.' It breaks down vague 'good usability' into observable data (e.g., how many seconds the task completion time decreased).

A five-dimensional metric system for quantifying user experience: Happiness, Engagement, Adoption, Retention, and Task Success. The mechanism is **data-driven experience**—breaking down vague 'good usability' into observable metrics, so that experience no longer relies solely on the boss's feeling, but can be tracked and improved with data.
