In what ways can companies effectively measure the success of their design changes in enhancing productivity and user experience, and how can they use this data to inform future design decisions?

Companies can measure the success of design changes by tracking key performance indicators such as user engagement, conversion rates, and task completion times. They can also gather feedback through surveys, usability testing, and user interviews to understand the impact of design changes on user experience. By analyzing this data, companies can identify patterns and trends that inform future design decisions, allowing them to continuously iterate and improve their products or services based on user needs and preferences.
