Central planning in a complex world


If the world is too complex to allow for long range planning, what should central management be spending its time doing?

As all the parts of the world, on many scales, start colliding and interacting, we now find ourselves inside what scientists would call a "complex adaptive system."

In that kind of world, nothing works the way you think it will, and everything has "unintended consequences" or "unforeseen side-effects." So, we might think that long-range central planning is impossible.

As usual, we're both right and wrong, and the situation is, well, "complex" and nuanced, and depends on what you mean by "planning."

Certainly "central planning" as practiced by Stalin in the Soviet Union or Mao in China ran into many unintended side effects, of the kind where millions of people died because the plans didn't seem to relate to reality on the ground.

But, today, with advanced supercomputers and high-speed global communications, now we can do central planning, right? Nope. Before the problem was too little information. We zoomed right past the sweet spot of "just the right amount" of information, and now we're deep into "too much information!" and heading deeper at an ever faster rate.

So, yes, we could deliver the equivalent of a moving van full of 3-inch binders to a small leadership committee every day, and ask them to read that, digest it, and plan based on it -- but I think the problem is obvious. That will simply never work. There is not enough "bandwidth," regardless how "smart" those people are , even to read that much new information, let along digest it well enough to grasp the implications in "real-time."

All technology is doing is further swamping the system, and that will never get better.

Actually, it's getting worse, because of the problem I've talked about before that information is "context-sensitive" -- that is, the meaning of some "fact" is really only evident if you understand the context of the observation of that "fact. " You can't just snip a fact out of context, slide it over to a central place, and expect it to mean the same thing there that it meant in context.

We all are familiar with this problem, yet, socially, we keep on pretending that it is some sort of local breakdown and that this is not a universal law. The problem is that it is a universal law. Information is not only context dependent -- it gets worse. Information is basically "fractal", like an evergreen where every branch, if looked at by itself, is the same shape as the tree, and each of its branches is the same shape, etc. There is, in other words, an infinite amount of information buried behind every detail, and under every rock, and in every "can of worms."

To try to "consolidate" this information and avoid the "moving van" of binders, each level of management "condenses" the information and "simplifies it." That process, alas, is "lossy", meaning, frankly, it doesn't work most of the time. What gets lost in translation are the key "details" that seem unimportant but that add up to changing the entire conclusion and outcome.

So, this cannot be fixed by having "even smarter" people at the top of this pyramid of information distortion. By the time information gets to the "war room" all the relevant detail has been stripped out by well-meaning intermediaries. And, you can't skip the middle because the volume of detail is too much to handle, again regardless how smart you are.

So, what to do? The only way to deal with this is to realize that the concept of central planning and central "control" is fatally flawed, and to push decision making outward, and delegate it down to as close to the decision as possible, where it still makes sense.

So, we find in The Toyota Way, an emphasis on Genchi Genbutsu, or "go down and look for yourself, because whatever they told you is going on left out something important that will change your decision once you see it."

This is not because the people "at the top" are not smart -- it's because "smart" doesn't matter if you were handed the wrong problem to work on, and the wrong facts about it to use.

It is what is known as a "system problem" and it is "structural." It will not go away with better information processing. The details cannot always be ignored. In fact, most of the time the details matter. Information is not "compressible" on the huge scale we're trying to operate on these days.

So, again, what to do? If central planners cannot plan actions, there is still one thing they can do, and that is to plan processes that, when distributed out, will result in coherent and successful action.

(Actually I think it's even one more step removed, and the best they can do is to plan processes that will lead to emergence of local processes that when carried out locally, times a billion, will result in correct and coherent action - even in the total absence of a "central plan." )

This is the problem that Computer Science is dealing with today, under the handle "emergent computing" or "evolutionary computing" or "swarm computing" or some such thing. This is the problem IBM has to solve for the "operating system" for their supercomputer (Big Blue?) that is really 860,000 computers consulting with each other about what each of them should do next.

So, the literature and research on this topic is buried in Computer Science, where managers and policy makers seldom tread.

The key take-away message, though, is that the problem for today, as viewed by Complex Systems people and Computer Scientists, is how to develop, discover, or evolve processes that lead to processes that lead to coherent adaptive action of the whole swarm.

Interestingly, as I understand it, that is largely the central focus as well of the Baha'i Faith, which focuses on finding what processes lead to the emergence of locally relevant decision-making processes that still combine and work together instead of fragmenting so that the whole thing hangs together with central unity and yet the power of local eyes dealing with local issues, while percolating larger issues upwards and getting guidance on those downward.

This is the exact same focus that the Institute of Medicine has realized needs to be done to make health care safer, as described in "Crossing the Quality Chasm" -- local teams, which they call "microsystems", have to be realized and empowered to be self-managing based on real-time local information and feedback -- while, at the same time, still participating in larger scale coherence that can follow patients and patient care as it crosses from one such team to the next.

And, this is the same focus that Public Health has, as I learned at Johns Hopkins over the last few years. Aid and support for any group, whether teen-smokers in some rich suburb, or indigenous people in some remote country, has to be "culturally relevant" and rooted in local action, or it will suffer "tissue rejection" and be thrown out as soon as the intervention is over.

Central planning can realize there is, say, a problem with malaria that crosses teams, cultures, and nation-state boundaries - but the action has to be locally meaningful and sensible and fit with what else is going on locally, or it cannot work. Solutions cannot be imposed from above, as those that attempt to do so keep on discovering. Too much information is lost at the top.

I think these seemingly disparate groups need to pool their notes and cross-fertilize each other's thinking, because this is all the same problem surfacing in different places, manifesting itself in different worlds.

I guess if no one else is going to do that, or has already, it's time for me to start a "Wiki" so everyone can hang their fragment of knowledge on that framework and we can start to see what it adds up to, and where someone else has already solved that part of the problem.

Wade-
Good thoughts.

This sounds very close to genetics. Contexts switching "genetic plans" "on" and "off" in a complex environment. Like grand plans, nature is not centralized, but it is selective. Diversity is key to survival as only individuals programmed by nature (and smart enough to take advantage) will flourish. Some may care to share their immunity or teach their unique lesson.
