In the dynamic realm of Extreme Programming (XP), the Developer Experience (DevEx) plays a pivotal role in shaping the efficiency and innovation of software development teams. This talk delves into the critical aspects of DevEx within the XP framework, highlighting the systems, culture, technology, and processes that underpin successful agile practices. We will explore practical strategies to optimize development environments, ensuring they foster creativity, efficiency, and job satisfaction among developers. By integrating improved tooling, streamlined processes, and a supportive culture, we aim to elevate the overall effectiveness of XP teams. Through real-world examples and actionable insights, attendees will learn how to address common DevEx challenges, measure the impact of their improvements, and sustain high levels of developer engagement and productivity. This session is designed for agile practitioners, team leads, and developers seeking to enhance their team's performance and well-being in an XP context, ultimately leading to the delivery of higher-quality software and more innovative solutions.
