Praise or complaints given from users about your digital product and how effective the product is at solving their problems.
Here's an analogy.
Like Yelp reviews, user feedback represents what your users have to share about the experiences, feelings, and thoughts they associate with your digital product. Sometimes, this means feedback might only consider the extremes—like a Yelp reviewer building their entire opinion of a restaurant from one bad visit.
Why does it matter?
User feedback is vital to gauge how your product is being perceived and where value is being realized.
How does it apply?
You can use feedback to determine patterns that will contribute to shaping your product roadmap. User feedback can be received in the form of formal interviews or focus groups, or it might be feedback that you get from the customer support team or sales team as they talk to customers.
