This episode discusses Systems Theoretic Process Analysis (STPA), a method for analyzing complex systems. Theo Klein, a Google SRE, and Jeffrey Snover, a Distinguished Engineer at Google, explain that STPA focuses on identifying how system accidents and losses occur due to a loss of control, rather than component failures. STPA helps identify design flaws early, even before code is written! The discussion highlights that STPA is a human-driven process, prompting critical questions about system goals and potential losses, and that Google is adapting the pure STPA approach for commercial software development to make it more practical and efficient.
