HEART framework

A framework for measuring user experience through Happiness, Engagement, Adoption, Retention and Task Success.

Also known as: Google HEART framework, Happiness Engagement Adoption Retention Task Success

HEART is a user-experience measurement framework developed at Google.

It covers five areas:

Happiness measures satisfaction and perceived quality.

Engagement measures the depth or frequency of use.

Adoption measures how many people begin using a product or feature.

Retention measures whether they continue using it.

Task Success measures whether people can complete an action accurately and efficiently.

A team does not need to track every category. The useful measures depend on the product and the behaviour the team wants to understand.
