Process-centered design is when designers make things easier for people to use, like websites or apps. It can be used to make things more enjoyable or easier to use. For example, when you go to the store, the shelves are arranged in a certain way so it's easy to find what you're looking for, like putting all the candy at a child's eye-level, or putting all the toothpaste or shampoo together in one section. This is process-centered design, making it easier and more enjoyable to shop.
