[SE #2] Thinking: Entropy, SysML v2, and the Physics of Agile

In this video, we explore the essence of Systems Engineering through the eyes of a 20-year automotive system architect. We move beyond the definition of a system as a mere "collection of parts" to understand it as a dynamic phase space where the force of Entropy (disorder) clashes with Negentropy (order).

[Key Topics Covered]
• The Physics of Systems: How the Second Law of Thermodynamics applies to software architecture and organizational management. We discuss how "technical debt" is essentially a localized increase in entropy and how systems require constant energy input to maintain order,.
• Emergence & Phase Transitions: Understanding how micro-level interactions create macro-level behaviors, such as vehicle stability or the catastrophic "thermal runaway" in EV batteries,.
• The Revolution of SysML v2: Why we are moving from SysML v1 diagrams to textual notation. We demonstrate how SysML v2 uses part def, action def, and strict semantics to treat systems as precise code rather than ambiguous drawings,.
• Agile as Control Theory: Reinterpreting project management using PID controllers and feedback loops. We compare the Waterfall model (Open Loop) to Agile (Closed Loop) and explain why rapid feedback is crucial for survival,.
• Real-World Case Studies: An analysis of automotive failures, including the trade-offs in EV battery separator design that lead to fires, and the conflict between suspension tuning and seat comfort,.
