Complexity
Many management and leadership scholars have been attracted to Complexity Theory, which originated in numerous fields of scholarship in the natural sciences (Dooley, 1997). An introduction to complexity will be a useful starting point in this book, although it is important to recognise that the translation from natural science to management science creates some wrinkles that will need to be explored later. Nevertheless, a basic definition might be:
Complexity is a characterisation or condition of the behaviour of a system, model, or other context – as a whole or within its constituent parts – all behaviours (interactions) guided by localized rules with no higher instruction evident. (Johnson, 2001, p. 19)
A very critical implication is that complexity can be studied and described even though the outcomes of the system, as far as can be known, are unpredictable. This makes the ability to quantify and assess threats, opportunities, and likely outcomes a challenging – and frustrating – task (Plsek, Lindberg, & Zimmerman, 2005). Systems theory, an affiliated concept, frames the study of complex behavioural patterns among interdependent agents in a social system whose purpose, structure, and functions are influenced by environmental forces (affecting parts of or an entire system). These forces and responses can appear chaotic and counterintuitive. They are certainly primarily nonlinear, since the observed effects of the individual parts cannot be easily aggregated into a cohesive whole – which is why the ability to predict escapes us. Chaos theory, also a related concept, among other things, considers dynamic systems that seem to occasionally reach disordered states, and identifies patterns between linked effects and feedback loops where a small change in one state of the system can cause large effects in a later state (Gleick, 1998). Climate change is an example of such system dynamics.
Complex systems can create spontaneous order – often referred to as self-organisation – formed by interactions between local parts, or agents, in an otherwise disordered context. Self-organisation is not the result of organisation-wide controls, but rather the actions by/among individual agents responding to various stimuli. Organisational multi-agent systems reveal a form of a self-organised system composed of autonomous interacting intelligent agents that can resolve emergent problems through negotiated solutions based on updated (often supported by digital technology) information (Mařík et al., 2002).
As a further extension, a complex adaptive system (CAS) gives shape to a dynamic network of interactive agents where the agglomerated, or collective, effect of their combined behaviours can be adaptive and innovative. That is, together the individual responses mould and reshape the system so it becomes more compatible with its environment.
Research on complexity has brought some important perspectives to management science, including the idea of organisations as CAS (Weaver, 1948). As with complexity itself, there are numerous variations of the CAS concept, but the major attraction for management scholars is the belief that CAS can provide remedies for the limitations of traditional linear and deterministic strategy modelling (Dooley, 1997). What does all these mean for thinking about risk management? Some influences are obvious, but others only reveal themselves on closer examination. A summary of the key insights would be the following:
Adaptation and innovation are the two central responses that agents employ to address challenges (challenges including, of course, risks, uncertainties, the unknown, and emergent phenomena).
The fundamental operational feature of CAS organisations is that all agents (employees, managers, etc.) have unfettered ability to work with all other agents in order to assess and address threats or opportunities. These interactions may be seen as unconfined individual actions but might also be conceived as operating within organisational systems.
CAS feature local rules (called schema) that guide individual agent’s judgement, decision rules, and behaviour. By use of the term ‘local rules’ it is suggested that the system is not hierarchical, nor does it operate in a centralised fashion. Everyone has a role in adapting to new conditions, innovating when necessary, and otherwise monitoring for challenges to the system.
Leaders in CAS have different roles. Two management scholars recently observed that leaders in CAS are expected to … ‘Facilitate … (b)oundary spanning, organizing and implementing aligned actions, promoting cross-functional training, joint planning and decision-making, deploying resources across units to foster interconnectivity’ (Uhl-Bien & Arena, 2018). This is sometimes called complexity leadership.
It may sometimes be said that CAS are ‘naturally regulated’, by factors like gravity and biological constraints. In organisational systems, questions abound as to what structures may need to be built to acknowledge artificiality. In other words, naturally regulated CAS are regulated by natural laws, while organisations have to recognise that the ‘regulations’ that bind them must be imposed and managed by humans.
The concept of Complexity Theory introduces a set of ideas that will shape the content of future chapters, as well as changes in risk management thinking. But perhaps the additional point to be made here is that our world is made up of many complex systems, and these systems represent ‘units of measurement’ that provide some degree of meaning. However, these systems ALL may be interconnected in various ways. And so here we must come to terms with – but ultimately learn to live with – the realisation that Everything is Connected, a phrase that will be repeated throughout the book. Within limits, we can understand specific components of a complex system or systems but it remains fully beyond our ken to clearly understand the interconnectivity of all systems to one another.
This is a humbling matter, and indeed humility is suggested as an essential quality for risk managers and leaders later in the book.
