How to approach complexity?

What we’re dealing with

When dealing with issues of design, planning, and organizing, we have to face both complicated and complex problems. A complicated problem is something that might be difficult, but still understandable and predictable. For example, building a watch or a bridge might be very difficult, but still something that we can understand and deal with careful planning. However, many problems are complex, meaning that they are difficult to understand and explain thoroughly. These kinds of problems, also known as messes (Ackoff, 1974) or wicked problems (Rittel & Webber, 1973) require different kinds of approaches and thinking than what we’re normally using in our daily lives.

Where do these problems arise? In an earlier blog post I briefly discussed the concept of SOHO systems (Kay et al, 1999, Kay and Schneider, 1994). SOHO is an acronym for Self-organizing, Holarchic, Open systems. Let’s take a closer look:

  1. Self-organizing means that when the system is pushed from its equilibrium, it might exhibit spontaneous coherent behavior and organization.
  2. Holarchic means that the system is formed up of part-wholes, i.e. holons, and is itself a part-whole. These part-wholes have dynamic interactions both horizontally and vertically across different scales of space and time.
  3. Open means that the system exchanges matter and energy between its environment.

SOHO systems are therefore dynamically relating part-wholes where non-linear feedback loops result in self-organization at different scales in the holarchy. What’s more, when these SOHO systems receive energy from their environment, they develop new structures and processes that make them more effective at receiving energy from their environment.

Ecosystems and human activity systems are prime examples of SOHO systems, both of which exhibit spontaneous coherent behavior and organization, are formed up of part-wholes, and are open. The messes that we face are the result of these dynamic interactions: as we have changed the environment we live in, we have created new and unpredictable changes in ecosystems.

What to do then? When we can’t predict our environment, we need to be able to coevolve with it, and this is where the concept of resiliency comes in.

Design systems for resiliency and learning

First, what is resiliency? From what I’ve learned, there’s at least two views on what resiliency means. The first, engineering approach, says that a resilient system is one that can take on outside shocks and quickly return to equilibrium. The other view, social-ecological resilience, says that a resilient system doesn’t have only one equilibrium, but instead can shift between different states, and learn, change and adapt.

In a wonderful article from 2006, Carl Folke had this to say about social-ecological resilience:

“Adaptive processes that relate to the capacity to tolerate and deal with change emerge out of the system’s self-organization. Furthermore, the dynamics after a disturbance or even a regime shift is crucially dependent on the self-organizing capacity of the complex adaptive system and the self-organizing process draws on temporal and spatial scales above and below the system in focus.”

Without going too much into details, the way I understand Folke is that resilient systems have the capacity to self-organize and create new structures and processes after a disturbance. Moreover, this capacity to self-organize is not a characteristic of one scale in time and space, but is derived from scales both above and below the system, as well as from different scales in time.

I think this point about different temporal and spatial scales is absolutely key here. The way we usually design human systems is by taking a look at one scale or holon at a time. When doing organizational design, you don’t usually start designing the whole that contains the organization. However, based on what Folke said, the capacity to self-organize is not contained at one level of time and space, but draws from all the other scales as well. This is why it’s about social-ecological resiliency, not only human resiliency. Building resiliency in one level will not be enough, and is in fact an illusion.

This also poses a major challenge to planning and design. How to design for resiliency when resiliency is not dependent on any one system? How can we ever build the capacity to self-organize when we can only affect a small part of the whole system at a time?

It would sound that enabling resiliency in our systems requires a paradigm shift at all levels of design. To enable resiliency, we need to change the organizing principles at all scales of social-ecological organization. How exactly are we going to get that done will have to be left for another discussion.

A brief discussion about boundaries and perspectives

Boundary judgments and the Hierarchy theory

In the second session of Systems Thinking 2 course at Aalto University we had an interesting discussion about boundaries and perspectives. One particular remark was made about boundaries, power, and decision-making. In all decision-making settings it’s important to be able to identify who gets to set the boundaries for decision-making. Often, especially in politics, people who have the most power are the ones who get to frame or reframe issues. This is important to understand because the problem-definitions we choose inevitably limit the different alternatives we consider for solving the issue. All kinds of questions are being answered for us when we allow someone else to set our boundaries, including who, what, why, when, and how?

The importance of boundary-setting and framing becomes even more evident when dealing with complex systems, and I dare to claim that most political issues are concerned with complexity. In complex systems, the dynamic interactions between the parts of the system and between the system and its environment make it difficult to predict the outcomes of our actions. It’s anything but easy to decide which interactions to consider in our decisions and which to leave out. So, when we allow others to define the problem space, not only are we placing a lot of faith into their hands, but we also give up much of our decision-making power.

The link between boundary-setting and decision-making is explained well in Hierarchy theory. In Mario Giampietro’s (1994) words:

“It is commonplace to experience a discrepancy in values when assessing the same phenomenon or action from different perspectives. For example, what is good to our taste (assessment on a short timescale) may be harmful to our health (assessment on a longer timescale); the lifestyle of singles is changed after marriage when the same individual becomes part of a larger structure, the family. This pattern is repeated at each enlargement of perspective that brings another hierarchical level into the picture: what is profitable for the family – less taxes – may be harmful to the community to which the family belongs.”

Where are you setting your boundaries?

Where are you setting your boundaries?

This means that decisions at one point in time and scale may affect either negatively or positively the situations in another point in time and/or scale. When we set the boundaries for decision-making at one scale, e.g. the economy, other scales and time-frames might be left out. We could also be neglecting other values and worldviews if we’re not careful.

However, change of boundaries might not lead to changes in perspective. Even when we point out that short-term changes in our economy might in some cases lead to degrading environment (and degrading economy in the long-term), we might still get stuck on the short-term economic perspective. A person might still view that improving the economy creates enough benefits in the short-term to justify lack of consideration for the long-term. In the end, we also have boundaries to our rationality.

Complexity as a matter of perspective

We also had a brief discussion about the nature of complexity. One of our teachers, David Ing, brought up a thought by Timothy F Allen, who had stated that complexity isn’t necessarily an innate characteristic of a system, but rather a matter of perspective. For example, the Apple iPhone might seem complex (or complicated) on the inside, but is relatively simple to use on the outside. A system can therefore be perceived simultaneously as both complex and simple, depending on your perspective.

Let’s take a closer look at the Apple ecosystem. I don’t have an engineering background, but from what I’ve understood, all Apple products taken together basically form an integral system architecture as opposed to a modular one. In a modular system or product architecture the different components of the system have high independence from each other. Thanks to this high independence, components of the system can be relatively easily disassembled and recombined into new configurations, and new product variants can be realized without much difficulty because changes to one component doesn’t lead to changes in other components (Voss & Hsuan, 2011.)

Lego bricks allow modular design.

The opposite of modular system or product design is an integral design, which I think Apple has chosen for its system. With an integral architecture, components of the system or product are tightly coupled, meaning that modifications to one component require redesigning or re-configuring other components. Apple’s iPhone, Macbooks, the iPod and all other products are all highly integrated to each other. To my understanding Steve Jobs felt very strongly about creating a seamless user experience for Apple products, which he ensured by retaining a strong control on any product modifications. You can’t even change the battery of your iPhone without expert help, let alone start making modifications to the design. Even the chargers to Apple products are different from other manufacturers who mostly use universal chargers.

However, although Apple’s products form an integral system architecture from the perspective of the underlying hardware and software, the Apple Appstore is far from integral. Millions of applications have been created by app-developers all around the world for the Apple iPhone and iPad devices. I think that is an extremely interesting design choice, whether consciously done or not! Ensure efficiency and reliability where it counts (hardware and basic software), but allow variety where people really want it (applications).

So, from one point of view the Apple system is complex, from another simple.
