Complexity Management Theory

"Given that the key finding claimed for complexity theory is the effective unknowability of the future, the common assumption among managers that part of their job is to decide where the organisation is going, and to take decisions designed to get it there is seen as a dangerous delusion. Management, afflicted by increasing complexity and information overload, can react by becoming quite intolerant of ambiguity. Factors, targets, organisational structures all need to be nailed down. Uncertainty is ignored or denied. The management task is seen to be the enunciation of mission, the determination of strategy, and the elimination of deviation. Stability is sought as the ultimate bulwark against anxiety, which might otherwise become overwhelming. All of these managerial reflexes, many of them seeming unassailably commonsensical, are (we shall see) quite counter-productive when viewed from a complexity theory perspective." Stacey (1993)
Now it's about preparing for chaos as defined by actions that defy predictability. Was the housing crash of 2008 unpredictable? Most models used by City Managers would not have shown any evidence of the market changing so radically, but was it unpredictable?
