There are a few well-known product metrics frameworks used by product teams to structure their data tracking. Let’s look into each of them in detail.

HEART framework

The HEART framework was developed by Google to measure and improve the user experience of their products.

HEART is an acronym for the five dimensions along which teams work:

• Happiness: how satisfied users are with the product
• Engagement: how often and how much users interact with the product
• Adoption: how many customers use the product regularly to solve their problems?
• Retention: how many users return to use or buy the product again over time?
• Task success: how well can users complete their objectives using the product?

When working along each of the dimensions, you start by setting the overall goals, then pick signals that will show you if you’re making progress and metrics that you’ll track to measure it.

So, if your happiness goal is to make the product helpful, fun, and easy to use, the signals could be good customer feedback, perceived ease of use, and recommendations. To measure them, you could choose metrics such as NPS or CES and look at reviews.
