Granularity, abstraction & coherence 1 of 2

Now while all of this has seemed self-evident to me over the years and has been reflected in many of our methods and tools, I’ve been sensing over the last five to seven years an underlying pattern that links back into quantum mechanics, biological scaffolding a range of other natural science material.  The move of biology or at least micro-biology away from taxonomies was a key part of that.  Part of the reflection process is attempting to distil both practice and theory into fairly simple, and ideally memorable heuristics.  I did that some years ago with Knowledge Management and the seven I identified have stood the test of time.  I composed numbers one, two and seven of those in a state of anger (and a big consultancy speaker who proceeded me was the provocation)  in five minutes on the Novartis Campus in Basel over two decades ago but they distil almost a decade of theory and practice.  I find that simple forms of complex, longitudinal understanding tend to come together quickly in conditions of righteous indignation, one of the more creative types of stress.

I also worked the same approach when I identified three aspects of managing a complex system.  There isn’t one single post (or if there is I can’t find it) which summarises them but in a simple form they are:

  1. Optimise the granularity
    Which generally means a high level, not a low level so more detail, less aggregation and less summary 
  2. Distribute Cognition/interpretation
    Put more simply, get lots of people from lots of backgrounds to interpret raw data, or the same data, in parallel without consultation 
  3. Disinter-mediate the decision makers
    that is to say remove interpretative layers between the decision maker and the raw data

Now I am not yet at the point where I am going to revise those, but I am getting there.  But I am starting to see three things as of considerable importance in managing complex situations and playing with those three as a way to achieve different results.

In part what I seek to achieve is to entangle things in novel ways to allow new patterns to emerge, or to create manageable stabilities where there is considerable flux or uncertainty.   The whole point of the work on substrate management, which is held under the working title of Estuarine Mapping, is to avoid commitment to solutions until a low-cost solution or solutions becomes more evident.  Don’t jump to solutions instead seek to change the energy gradients so that what is sustainable will emerge.

What will emerge is of course unpredictable.   If we look at the discovery of super-conductors by experimental not theoretical physics we have a good example.  Superconductivity could not be predicted from the behaviour of electrons, but given sufficient clustering, the phenomena were observed – the properties of a whole cannot be decided from the properties of the parts.   So finding ways of reducing the distance between things increases the change of novelty and, critically the chance to discover new forms of resilient stability that allow you to manage uncertainty.

And that brings us to the essence of a complex adaptive system.  As a reminder a CAS consists of many elements (necessary but not sufficient) with rich, in the main short range interactions; it’s also open and the elements or agents are ignorant of the whole.  That quick summary explains why the idea that systems are defined by boundaries and the suggestion that we should think holistically really doesn’t match with Complexity Science.   But as those rich and short-range interactions start to feed back, stabilities form in the system.  Those stabilities or emergent phenomena have qualities that cannot be predicted from the qualities of the elements that make them up.

So that pulls me into getting to some basic heuristics for understanding how we can manage a complex system.  The argument is that if we increase the number of elements and intensity of the nature of the short-range interactions then we are more likely to stimulate the emergence of novel structures and because we are actively managing those interventions we can spot emergent patterns early and amplify the ones that appear to be beneficial and disrupt those which are not.  And, critically we need to do this in human systems; which have added layers of complexity to say a termites nest of the flocking behaviour of birds.   So for human systems, our work is always going to be trans-disciplinary; complexity science is a key enabling constraint but it is not enough of itself and it’s certainly not a metaphor.

I recently put out a simple statement, designed to fit within the character limits of a tweet on all my social media platforms which said:

‘Complex theory gives rise to simple methods and tools that work at scale; simplistic theory gives rise to increasing complicated methods that create excessive dependency on consultants’   Discuss

Now a lot of people thought that I meant complexity theory and if I am honest I knew I was setting that up.  But I was actually talking about the need to create trans-disciplinary theory in order to design simple methods and tools.  That means integrating different theory bases which by it’s very nature is a complex process.   Using a single theoretical base is simplistic and you, therefore, end up with increasing levels of complication as you haven’t stated in the right place.  So you keep patching on amendments to deal with exceptions and as a result, you end up in a place where it’s difficult for the non-expert to engage.  The complicated language of systems dynamics and cybernetics reflects that.

I should also be clear that shifting to higher levels of granularity is not about revealing some form of an underlying set of essences, a universal fundamental reality from which everything else is built.   High granularity in effect increases variety it doesn’t reduce to some essential form.

So that ends up with three aspects of the complex system around which I can develop heuristics namely granularity, abstraction and coherence.   Tomorrow I will pick those up in more depth
