Structural relations define which parts are connected together. Structurally complex system A system that can be analyzed into many components having relatively many relations among them, so that the behavior of each component can depend on the behavior of many others.

COPING WITH COMPLEXITY Coping with the complexity of today’s business environment is not about predicting the future or reducing risk. It’s about building the capacity, in yourself, your people, and the organization to adapt continuously and learn speedily, in order to maximize the chances of seizing fleeting opportunities. These authors’ excellent suggestions will help today’s leaders cope with complexity. As business leaders, policy makers, the academic community, the media and an outraged public search the rubble of the global economic crisis for clues as to what went wrong, all fingers point to a common perpetrator, poor risk management. But while risk management, or lack thereof, played its part in the disintegration of the world financial system, we contend that another culprit played an even bigger role: complexity, and an inability to cope with it. Complex environments, complex organizations Complexity is one of the salient hallmarks of the 21st century. 1. 2. 3. 4.
How Schools Can Teach Innovation caos La vita si evolve verso un regime di equilibrio tra l’ordine e il caos. Suggestiva l’immagine che la vita esiste ai confini del caos. Quasi come se la vita esistesse in una sorta di transizione, nello stato ordinato adiacente alla transizione di fase che porta al caos. I sistemi che si trovano nello stato ai confini del caos - un compromesso tra l’ordine e l’imprevisto- sono quelli che meglio sono in grado di coordinare attività complesse, e allo stesso tempo di evolversi. Il mondo vivente è abbellito da una sovrabbondanza di ordine. Vengono considerate reti, in particolare reti booleane, ed esaminati i cicli di stato che in esse si formerebbero. Si può regolare la connessione della rete e modificare le regole di controllo. Proprio in mezzo, tra l’ordine e il caos, vicino alla transizione di fase, possono verificarsi i comportamenti più complessi: abbastanza ordinati da assicurare una stabilità, ma pieni di flessibilità e di sorprese.

The Pretense of Knowledge - Friedrich A. Hayek [Lecture to the memory of Alfred Nobel, December 11, 1974] The particular occasion of this lecture, combined with the chief practical problem which economists have to face today, have made the choice of its topic almost inevitable. On the one hand the still recent establishment of the Nobel Memorial Prize in Economic Science marks a significant step in the process by which, in the opinion of the general public, economics has been conceded some of the dignity and prestige of the physical sciences. On the other hand, the economists are at this moment called upon to say how to extricate the free world from the serious threat of accelerating inflation which, it must be admitted, has been brought about by policies which the majority of economists recommended and even urged governments to pursue. This brings me to the crucial issue. As a profession, economists have made a mess of things. The essays for which Hayek won the Nobel Prize

Complexity, patterns and links The mainstream ways of thinking about management are based on the sciences of certainty. The whole system of strategic choice, goal setting and choosing actions to reach the given goals in a controlled way depends on predictability. The problem is that this familiar causal foundation cannot explain the reality we face. Almost daily, we experience the inability of people to choose what happens in their organizations – or in their countries. We live in a complex world. Things may appear orderly over time, but are inherently unpredictable. Complexity refers to a pattern, a movement in time that is at the same time predictable and unpredictable, knowable and unknowable. Human patterns that lose this complexity become repetitive and rapidly inappropriate for dealing with life. A pattern is something that emerges through the complex interactions between elements in a system. Patterns that are more repetitive are normally called routines or habits. Like this: Like Loading...
