User experience (UX) plays a critical role in software design by shaping how users interact with the application. It encompasses all aspects of the user's interaction, including interface design, accessibility, and workflow. Prioritizing UX means creating software that is intuitive, efficient, and enjoyable to use, which can significantly impact user engagement and satisfaction. Effective UX design can lead to lower training costs, reduced user errors, and higher productivity, making it an essential component of successful software development.
