In an increasingly interconnected world, both software systems and organizations exhibit behaviors of complex adaptive systems. This talk will explore foundational principles such as self-organized criticality, power laws, small-world networks, and emergent behaviors. Using real-world examples from software architecture and human organizations, we will see how CAS concepts can drive adaptivity and innovation. The discussion will offer valuable lessons for software engineers, quality management, and process managers, equipping them to navigate the dynamic nature of modern systems.
