In this video, we explore: The principle: According to research (and Kevlin Henney’s insights), the more features added to a system—and the more complex they are—the greater the room for technical debt, with the biggest jumps often happening in bursts when new features are added quickly. Catastrophic real-world examples like Knight Capital Group (2012) and Southwest Airlines (2022), showing how rushed updates or decades of patching can lead to massive losses. Managing technical debt: How to measure it using the Technical Debt Ratio (TDR) and automated tools like SonarQube to keep your codebase healthy. Whether you’re a developer, product manager, or just curious about the hidden costs of software, this video shows why maintaining clean, manageable code is critical—and how to avoid letting technical debt spiral out of control.
