The term system often sounds too theoretical, ambiguous and we use it in many ways.
For clarity purposes therefore Ulanowicz, Goerner and Lietaer rather used the term “network”, and defined a system as a network of elements in flow of energy, matter and information.
Money flows
in the monetary system, water flows in the water system, information flows in
the Internet, in a country’s health care system we can see the flow of Corona
patients, as the stream of people infected by that virus flow through doctors,
hospitals, clinics, etc. With these streams of matter we can also see flow of
energy and information (like for Corona hospital budgets and information on diagnosing,
testing, tracking lines of contamination etc.)
A living system has two special features: it organizes and creates itself, serving one purpose: to sustain it. To survive.
Even we as individuals organize ourselves - continuously adapting as required to survive.
And we re-create ourselves continuously: we renew our skeleton every 10 years, intestines every 15 years, liver every 2 years, skin every 2 weeks.
Sustainability is a system’s property. To understand a non-sustainable situation, we must both identify the system we wish to understand and the flow we wish to make sustainable.
This term is used in many ways. Just look around and you will find these:
These multiple
ways of using the term sustainability Goerner, Ulanowicz and Lietaer distilled
down to this precise definition: “Sustainability is a network‘s capacity to
sustain flow of energy, matter and information”
This definition is a major breakthrough, a new frame of mind. It applies to all kinds of systems – forests, resources, investment, monetary systems, and it identifies one single indicator of performance: flow.
A sustainable
system enjoys unconstrained flow of energy, matter and information. Out of
balance it will not be sustainable. Just that.
A country’s health care system is sustainable if it can cope with each case of a Corona patient, rapidly and effectively. If however this flow is hindered or constrained it is not sustainable.
The term resilience also is used in many – sometimes contradictory ways. Here are some examples:
These multiple ways of using the term resilience Goerner, Ulanowicz and Lietaer distilled into this precise definition:
“A system’s or network’s resilience comprises two competencies
Corona is a shock for a country’s health care system. To be resilient against this shock it has – for instance – a sufficient number of intensive care beds available for patients with serious infections. For Germany Statista reports 33.9 such beds per 100.000 inhabitants in hospitals, while Ireland has a much lower resilience in that element with just 5 such beds.
We use the term efficiency in multiple ways, for instance to describe:
· Avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result.
· Internal performance of an organization like a business or a team
· Doing things right, well, successfully
· How well we transform input to
output
As examples we might describe the efficiency
of an education system by its cost, or the efficiency of a health care system
by how well it utilizes its assets.
In the same context we also use effectiveness, where we mean
· External performance,
· Doing things right
· The value of output to others, for
instance external or internal customers
For the law
of sustainability we define efficiency in a more specific way, as more
specifically as a network‘s capacity to perform in sufficiently organized and
efficient manner as to maintain its integrity over time.
For the case of Corona, efficiency means a country’s health care system’s capacity to maintain its integrity: sufficiently organized doctors, hospitals, tests and social rules.
