What does 'user experience' focus on in software development?

The focus of 'user experience' in software development is primarily on user interactions and satisfaction. This area emphasizes how users perceive and interact with software applications. In user experience design, considerations include usability, accessibility, and overall satisfaction with the interface and functionality of the software. This holistic approach ensures that the end product not only meets functional requirements but also resonates positively with users, ultimately enhancing their engagement and facilitating a seamless interaction.

In contrast, the other options concentrate on specific aspects of software development that do not directly address user experience. For instance, code quality pertains to how well the software is constructed from a technical perspective, while testing methodologies focus on verifying functionalities and identifying defects. Project management practices deal with planning, executing, and overseeing project developments and timelines, rather than the end-user experience. Thus, option B stands out as it encapsulates the core aim of user experience, prioritizing the user's perspective in software development.
