Deep dives

The Foundations of Extreme Programming

Extreme Programming (XP) emerged from the realization that technical mastery alone does not guarantee project success. Kent Beck discusses how early in his career, he focused on becoming a skilled programmer but discovered that effective relationships with business stakeholders and team members were equally crucial. This led to the identification of practices that enhance programming outcomes, such as continuous integration, where more frequent code integrations reduce the pain associated with merging code. By pushing the boundaries of effective programming practices, XP became a response to the industry's need for alternative development methodologies during a time of dissatisfaction with traditional waterfall approaches.
