DESCRIPTION
Kent Beck and Daniel Terhorst-North reflect on the evolution of Extreme Programming (XP) and its lasting impact on agile software development. They explore the importance of short feedback loops, iterative learning, and adaptability in different phases of product development, as outlined in Beck’s 3X model (Exploration, Expansion, Extraction).
Kent introduces radical techniques like Test && Commit || Revert (TCR) and Limbo, which challenge traditional coding and collaboration practices by emphasizing tiny, safe iterations. The conversation ties in psychological safety, a key factor in high-performing teams, as outlined by Amy C. Edmondson.
Kent envisions a future where software development scales in real-time, pushing teams to embrace faster experimentation, responsibility, and continuous learning in a rapidly evolving tech landscape.
