Why are user stories and user-centered design so important in the process of creating an app?

User stories and user-centered design are crucial in app development because they help ensure that the app meets the needs and expectations of its intended users. User stories outline specific user interactions and goals, guiding the development process towards creating a product that is user-friendly and functional. User-centered design focuses on understanding user behaviors and preferences, resulting in an app that is intuitive, easy to use, and provides a positive user experience. By incorporating user stories and user-centered design principles, developers can create apps that are more likely to be successful and well-received by their target audience.
