A violation of [[Occam’s razor]]; a source of confusion, a time-sink, a material contributor to catastrophic [[normal accident]]s; a ''[[waste]]'' — yet in a [[distributed network]] of autonomous bodies, a total inevitability. The more sophisticated the group of individuals, the greater the rate of complexification.

===Complication versus complexity===
===[[Complicated]] versus [[complex]]===
Things can be merely [[complicated]] without being [[complex]]. ''Complicated'' problems are naturally difficult, but you can solve them with rules and [[algorithm]]s. The systems and processes, by which The Man commands and controls employees can manage this kind of ''complicatedness''.

Is your system simple, complicated or complex?

*'''[[Simple]]''': suitable for checklists, recipes etc, where heuristics can overcome the hubris that comes with treating ''simple'' processes as ''trivial''.  Disinfecting your instruments before performing heart surgery is simple, but not trivial. See: {{br|The Checklist Manifesto}}
*{{simple capsule}}
*'''[[Complicated]]''': complicated systems need skilled management, but the right hands can usually manage them successfully. You know you have a complicated system when there is a comprehensive and robust set of axioms and rules, and thus it is a matter of making sure that the proper models are being used for the situation at hand. [[Chess]] and [[Alpha Go]] are complicated, but not complex, [[systems]]. They’re ''not'' [[wicked environment]]s. Do you hear that, {{author|Daniel Susskind}}?

*'''[[Complex]]''': Complex systems are dynamic, constantly changing, and interact with themselves and the environment in unexpected ways. They may comprise multiple other simple, complicated and indeed complex systems interacting with each other. So step one is to manage the simple and complicated sub-systems as effectively as possible — deploy checklists, simplify, homogenise — but even after that you are ''still'' left with a system which is innately unpredictable. It will do unexpected things. Like blowing up. So have your plans for dealing with those [[normal accident]]s.
