About this website

This is a website dedicated to understanding and navigating the complexities of change. This site explores the Actor-Based Change (ABC) Framework, a practical and useful tool for understanding how change happens in complex systems. It provides resources and insights on complex systems theory, and shares case studies of how the ABC Framework has been used to guide interventions and evaluation in real-world contexts.
