The intellectual architecture behind the newsletter, why it's structured as it is, how the topics connect, and where it's heading.

Overview

On Complex Systems covers general systems theory, its subdisciplines systems thinking and system dynamics, and organizational theory. It illustrates those concepts with real-world examples and provides actionable insights. The editions follow a progression from foundational thinking and scaffolding to how we analyze, design, develop or evolve, and adapt companies, economies, and societies.

1. Intro

  • How our methods to organize companies, economies & societies evolved (approx. 2 dozen editions covering tribal formation through the sociological view of systems)

2. Foundational Philosophy and Mental Models

  • How our methods to understand & solve problems evolved — the analytical approach vs. the systems approach
  • Purposefulness as a systems behavioral principle
  • How openness influences the dissolution & adoption of ideas

3. Behavioral Principles of Systems

  • Multidimensionality and the relations between opposing tendencies
  • Counterintuitive behavior of social systems
  • Emergence — the difference between the properties of the whole and its parts
  • Opinion: Why Friedman was wrong about the purpose of enterprise
  • Opinion: The interplay between innovation and stability
  • Self-organization — the essence of sociocultural systems
  • Culture's role as an "operating system"

4. Understanding Sociological Systems

  • Social learning — our difference to biological systems
  • The development of social systems and the multidimensionality of its theories
  • A systems view of how social systems are developed

5. Development of Sociological Systems

  • Impediments to the development of social systems
  • Holistic Thinking — iteration, verification of assumptions, dimensions of sociological systems
  • Operational Thinking — feedback loops, delayed reactions, nonlinear effects

6. Modes of Thinking

  • Design Thinking — rooted in Herbert Simon and Russell Ackoff; design as a systems method
  • Why a system's boundary & environment are everything
  • The role of purpose in designing an organization

7. Understanding & Formulating a Problem

In complex systems, problems rarely have a single cause. Across several editions, covering how to formulate problems in complex systems by mapping how they arise, persist, and interact — surfacing feedback loops, conflicting demands, and how structure, function, and process reinforce the current state.

8. Organizational Design

  • On alignment of functions, structure and process
  • Why organizational design is downstream of governance design
  • The essence of governance design: decision-making operationalization
  • The structural preconditions of organizational design
  • The essence of governance design: decision-making operationalization
  • The structural preconditions of organizational design

9 & 10. Analysis of Live Events & Closing Thoughts

After laying the foundations, the newsletter moves to analysis and commentary on current and live events, with cross-references to earlier editions. Guest authors from varied backgrounds will be invited to demonstrate how these disciplines play out in their own work.
