First and foremost, UX makes every day things usable, useful, relevant, and meaningful.
Second, UX helps you build empathy with the people who are using the product. This helps you to see the world through their eyes and build products that truly help them.
Third, UX helps you differentiate your product from the competition. Using the right UX methods, you learn about what competitors are doing, gaps in the market, and how you can do it better. It then helps you validate your designs to ensure that the product or feature will be a success before you’ve even launched.
And finally, UX helps create products that are accessible. Through testing and accessibility guidelines, you can make certain the products you create can be used by most people.
