OPEN SYSTEMS
by Regina Brooks and Vicki L. Walls (TNU 2008)
Systems
are a natural part of our everyday world. They are present in almost
every aspect of our lives. The universe we live in is a system and made
up of many subsystems. The creator of the universe and all his glory
weaved these systems and subsystems together to work, separate at times,
to produce the wonderful world that we live in. Even the very body that
we live in is a system and has numerous subsystems at work within that
are so complex that science cannot grasp all of it. In this paper, we
are going to deal with one aspect of these systems, the open and closed
system in organizations.
Ludwig von
Bertanlanffy developed the open system theory in 1956. A biologist in
nature, Ludwig defined a system “where all systems characterized by an
assemblage or combination of parts whose relations make them
interdependent” (Scott p. 77). They soon found out that this concept
could be applied to the study of organizations. The definition of a
system is “an entity, which maintains its existence through the mutual
interaction of its parts.” These groups or parts are dependant on
each other and work together toward the same goal. Characteristics of an
open system are:
1. input of information or parts 2. processes 3. goals 4. interaction with their environment 5. assessment 6. evaluation 7. learning 8. flexibility 9. organic
The closed system is
defined as having hard boundaries through which little information is
exchanged. It is often used to refer to a scenario where closure is
absolute. In practice, however, no system can be completely closed but
rather, will be a system with varying degrees of closure. (Wikipedia,
Closed System) The characteristics of a closed system are:
1. no feed back
2. mechanical
3. not dependant on environment
4. no output
5. no exchange of ideas
6. no influence on environment
7. stagnation


Organizations with
closed systems are unhealthy, stagnate, and over time will usually
dissipate. Examples of these kinds of systems are bureaucracies and
monopolies.
The
concept of systems can be illustrated by examining a system that most
people know very little about, the human system. Obviously, the human
system is something very complex. When this system works as designed,
most of us take it for granted. However,
When our bodies malfunction or become sick, there is much to consider.
The end goal is to fix the system or to become well again. In order to
accomplish this, it is necessary to look deeper.
Contained within the
human body, numerous subsystems are constantly at work. When any of
these subsystems fail to function as designed, the result may affect a
subsystem and ultimately, the whole body. It is not possible to “fix”
the body without addressing the problem within the subsystem that is the
underlying cause of the illness. Unfortunately, for many, this is not
always easy. Often other supporting subsystems are involved and
contributing to a chain reaction that in turn, ultimately leads to a
crisis for the entire body.
Being aware of how one
basic system works, such as the human system, will help with
understanding how other systems work. All systems are simply “a
collection of subsystems working together to accomplish an overall goal
(a system of people is an organization).” (McNamara) All open systems,
as do human systems, have input, processes, outputs and outcomes, with
ongoing feedback between these various parts. If one part of the system
is removed, the system is changed. If one part of the system is not
working well, the system is affected negatively (the body becomes sick).
Systems can range from
very simple to very complex and there are numerous types of systems. For
example, there are biological systems (the heart, respiratory, lymph,
renal, nervous, etc.) that make up the human system or the body. There
are also engineering, mechanical, social, ecological, and technological
systems. Each of these systems has numerous subsystems, as well. These
subsystems have different levels of significance (i.e. heart versus
nervous) but are integrated to accomplish the goals of the overall
system. Each subsystem has its own function and boundaries, and includes
various inputs, processes, outputs, and outcomes geared to accomplish an
overall goal for the subsystem. In the human system, the renal system
works to rid the body of any impurities through a filtering process. If
the kidneys fail to do their job, other subsystems will be affected and
ultimately lead to the death of the entire system.
When applying these
same principles to organizational systems, it is easier to understand
how the overall organization is affected by the operations of the
subsystems within. Organizations that understand this principle are
better able to see that the success of the company often depends on the
successful operations of the many subsystems within the company.
If an organization is
compared to the human body, the parallels are not difficult to make. A
typical organization chart would list the head of the organization first
with the major departments and direct reports listed next. These major
departments and their leaders would represent the major organs and
systems within the human body. Each major department of a company is
vitally important, has specific tasks and responsibilities and their
performance affects the whole organization. Each sub-department has
specific responsibilities and usually depends on other departments for
support and provides support for to other departments. This input/output
exchange works together to support the organization as a whole.
Open systems, closed systems, and system thinking in general may be
considered a new way of looking at organizations. The truth and
principles involved however have been present since the beginning of
time. It has just taken a long time for analysis and theorist to put
these concepts into writing. Open and closed systems in some form will
interface with the lives of every human being throughout life.
Understanding these concepts and learning to incorporate them in our
areas of work will help build and maintain healthy, highly functioning
organizations. These organizations will have a better chance of
surviving and thriving in the business world.
