This document discusses different levels of simplicity, complexity, and chaos in design. It introduces Thomas Vander Wal's Cynefin framework, which categorizes systems as simple, complicated, or complex. Simple systems have straightforward cause-and-effect relationships, while complicated systems can be analyzed systematically but may not be straightforward. Complex systems cannot be fully understood through analysis alone and require small, adaptive solutions. The document advocates embracing complexity rather than chaos by understanding core dimensions and interactions to improve design.
