User experience designers spend a lot of time observing users, talking to them, and gathering feedback. They track metrics like load time, crashes, and daily active users.
These experiments and numbers are invaluable for creating an effective UX — but they’re not enough. You need a holistic view of the overall user experience to make good product development and UX decisions.
So how do you get one?
That’s the question the UX Research experts at Google faced. The result? The Google Heart Framework, designed to help UX teams focus on specific aspects of the user experience they want to improve, as well as identify concrete goals and user experience metrics to gauge success.
The HEART framework is a set of user-centered metrics. It was developed to evaluate the quality of the user experience, and help teams measure the impact of UX changes.
The framework is a kind of UX metrics scorecard that’s broken down into 5 factors:
The HEART framework can be applied to a single feature in your app, or to your whole product.
Setting goals up front is a great way to get every member of your team on the same page. Is it more important to attract new users, or increase engagement for existing users? What tasks do you want new users to complete? Remember that goals for a particular product or feature update may be different than the goals you have for your overall app.
It’s important to narrow down your list of goals to no more than 3. While focusing on every aspect of the HEART framework may seem like a good way to build a near-perfect UX, it’s not practical to be juggling five goals and more than a dozen metrics.
Aditi Bhargava, a UX Researcher at Google, explains how her team narrowed in on a set of UX goals:* “What do we want a customer to tweet after using our product?”
For example, if you want users to talk about how easy your app is to use, focus on task success. If you want them to talk about how much they enjoy using your app, choose happiness.
Every goal has related user actions. Mapping your goals to those actions can let you know whether you’re on track. What behaviors or attitudes would indicate your goal has been met or failed?
For example, entering search text but not clicking on any of the results could indicate irrelevant results. Or an increase in time spent consuming content in the app would indicate higher engagement.
Finally, distill signals into trackable metrics that you can monitor in a real-time dashboard. For happiness, Net Promoter Score or Number of 5-Star Ratings would be a trackable metric. For adoption, Registration Rate may be a good metric to watch.
It’s easy to generate a lengthy list of potential metrics. Keep your list manageable by sticking to metrics that will actually help you make UX decisions.
Kerry Rodden, one of the original Google UX Researchers who originated the HEART framework, mentions an important consideration.* Your overall numbers will naturally go up as your user base grows, so make sure you normalize results. Ratios, percentages, and averages per user are more useful than raw figures.
