Marco Valente wrote a blog post titled Complexity theories and Systems Thinking: Parallels and Differences.
“Having an un-ordered nature, a complex system will not obey causal laws in the same way a complicated system does. An inclination of the system can be thought of as a predisposition, a very common habit, but when the system is indeed un-ordered, we need to forgo our hopes of predictive accuracy about what the system will do next.”
“At least since the times of economist Hayek, the angle from [complex adaptive systems] postulates that in complex systems there is no agent in it who has access to the entire picture.”
“Berger and Johnston have written the best book so far for leading in complexity… Berger and Johnston make a compelling case for why the traditional strategic planning made of milestones can actually even be counterproductive when the scenario is rapidly changing and uncertain. For instance, this can blind us to the fast-changing landscape around us, and make us miss emerging opportunities. They summarize a vision in a complex world in the following way:
‘In a complex world, a vision is not a photograph of a future destination, and a strategy isn’t the map that charts the course. A complex vision is a compass that points towards a future direction, and a complex strategy is a set of safety guardrails inside which people can innovate and learn.’”
“Peter Allen recently put it this way:
‘The key step that complexity added was to recognize that the ‘system’ itself could potentially redefine itself, evolve and change – qualitatively – creating new variables, new mechanisms and new emergent features and characteristics. Any system at a given moment has emerged from a past in which it was not what it is now. Complexity is about evolutionary emergence of structure and form. This involves ‘learning’ and ‘forgetting’ not just functioning – recognizing changed features and elements, requiring perhaps changed values, aims and goals. Complexity admits that the ‘functional structure’ may change – and life is not just a mechanical system running forward in time!’”
“Ontology is a branch of philosophy that investigates the nature of things, often in contrast to how we know things (epistemology).”
