This document discusses adapting organizations to a complex world based on principles from complexity science. It argues that organizations need to (1) undertake ongoing context analysis by looking widely at past, present, and future factors from macro to micro levels (2) be adaptive but not just reactive by experimenting, learning from sharing results, and allowing local interpretation within broad guidelines. While embracing complexity requires a difficult mindset change from wanting a predictable world, it can lead to greater effectiveness if organizations act congruently with the reality of complexity rather than trying to control a system that does not exist.
