These criteria, along with the Goals - Signals - Metrics evaluation can be applied to individual projects or across an entire product. HEART is a way to use attitudinal measures (Happiness) to predict adoption and usage statistics (Engagement, Adoption, and Retention) that can be tracked using task-based measures in usability testing such as Task completion rate and task time. The HEART framework builds off existing models.
