Complex Systems

There is a tremendous literature on complex systems out there, but I'd especially like to alert users of Wiki to some software being developed at the SantaFeInstitute called Swarm. See http://www.santafe.edu/projects/swarm/overview/overview.html. EdBuffaloe Check the new Swarm web site at http://www.swarm.org/

See also CeptualInstitute, which is looking for friendly and constructive people, asking "Your comments are welcome", but has not yet a WikiForum, what they really deserve.

http://complex-systems.ucsd.edu/ is a lab in San Diego studying complex systems.


The science of complex systems was first made popular by the SantaFeInstitute (SFI). This group of complex systems theorists and practitioners offer the following definition:

"Complexity refers to the condition of the universe which is integrated and yet too rich and varied for us to understand in simple common ? ways. We can understand many parts of the universe in these ways, but the larger more intricately related phenomena can only be understood by principles and patterns-not in detail."

This concept is important to us because the nature business and IT systems are becoming more complex. For almost a century our manufacturing model was reasonably stable. Rules for productivity, market dominance, and company success were well understood. However, the Information Age has turned previous "knowns" on their head. Today, no one can predict what or how rapidly new technologies will be developed. No one can accurately predict how supply chains will be affected or how customers will respond. A good business plan is only a guess.

Even small-to-medium-sized business are not insulated from this effect. Satellite communications, the Internet, and air transports commonly provide ways of rapidly moving corporate resources from place to place. All of us are now connected through a global market of online customers and suppliers, supply chain partnerships, and international franchise competition. As Susan Kelly and Mary Allison [1] suggest, businesses that don't understand the nature of complex system thinking and take advantage of it "will be at the mercy of an increasing number of sudden and unexpected shifts in the marketplace. As uncertainty grows exponentially with today's high rate of technological change and the fallout from it, so does the pressure of global markets." Many executives try to respond to this with yesterday's mindset and linear cause-and-effect thinking. Often, these responses will intensify an already downward spiral. Despite well-conceived plans and well-intended actions, a company that operates without complex-systems thinking will find itself unable to respond to the ever-increasing complexity of the business world.

Primary Issues

Common to any discussion of complex systems are several fundamental ideas.
