Any digital application design should allow for the users to report back their problems and issues they face while using the application. There is often an oversight on enabling feedback that would help making the experience better for users. Feedback can be gathered through various systems like ratings, surveys, help, contextual support. Choosing the right feedback mechanism is as essential as choosing the design itself.
Consider the case of a small business application for real estate in which the users browse through various property listings and book slots for open house viewing. A small glitch in performance could lead to a lot of time being spent in waiting for images or videos to load. Using a simple survey with rating mechanism could deliver the problems to the business. Missing out on such feedback might cost the business thousands of dollars in revenue.
