A SYSTEMS THEORY
APPROACH TO (EDUCATIONAL) ORGANISATIONS
BY A.B.FINLAY
Ph.D.
Systems Definitions
Attempts to define system are a
sine qua non of any consideration of systems theory and its
concepts. Of course, definitions abound. Basically they have
the same meaning and refer to an almost limitless number of
things “from the smallest ‘whole’ to the total universe.”
These systems clearly may be conceptual, concrete or abstract,
but they are all characterised by particular properties.
Immegart and Pilecki speaking of the notion of system define
it as “an entity composed of:
(i)
a number of parts,
(ii)
the relationship of
these parts and
(iii)
the attributes of
both parts and the relationships.” (An Introduction to Systems)
They broadly classify systems into
theoretical, conceptual, practical and ‘living’ or ‘physical’.
Fundamentally it is clear there are two categories that must
be identified: physical (or inanimate) and human (or animate)
and hence I differ somewhat from the above authors in the
meaning of the word physical. A very important point made here
by Immegart and Pilecki is that systems are distinguishable
from others by a “uniqueness of character”. Hodge defines
system: “any entity, conceptual or physical, that consists of
independent but interrelated parts.” (The
Systems Approach to Education). Banghart quotes a
definition of system (in
Educational Systems)
as “an integrated assembly of interacting elements designed to
carry out co-operatively a predetermined function” – though it
is possible to quarrel with the use of the word
‘pre-determined’ – I feel this is not always the case. Perhaps
the simplest of definitions is given by Romiszowski in his
introductory article to the mentioned book: “a system is an
inter-relation of parts.” (THE SYSTEMS APPROACH TO EDUCATION).
He then goes on to illustrate a simple system by reference to
a bicycle and by extension to its rider though it seems that
here a different element is introduced, i.e. the idea of the
application of kinetic energy to a system (though in fairness
to Hodge, he does say that it is possible to consider the
rider as an input to the bicycle system). However, the point I
am trying to make is that the bicycle when not being used is
still a system (according to all the definitions) but it is an
inert or static one; clearly, therefore, when used, the
bicycle is an active or progressive system. There is then the
idea of active and static systems, which must apply in both
respects only to physical systems: the bicycle, a clock
(running or stopped), a drainage system, etc. Where people
form the components of a system, the latter must be active (or
progressive, in some way); mainly, therefore, in education we
are concerned with the human and active system. Furthermore,
the concept of the simple system seems to be a useful one; it
would apply to the basic unit of a larger system and would not
have a sub-system of its own (the chain of the bicycle? the
individual teacher or student in the school system?). By
analogy with the field of syntax, one might conceive of the
compound and complex systems in addition to the simple. By
compound would be meant a system that while conforming to this
accepted definitions, consists of parts in strict sequence,
with a logical dependence of the one part upon the other (the
illustration of the rider and the bicycle, in its active form,
is one; a system of film projection is another). Complex
systems would be characterised by a simultaneity of moving
parts or active sub-systems, so that while the main process
(or activity) is developing so are others, complete but
obviously dependent on the main process for their meaning and
existence. Such might be an L.E.A. organisation or a school.
Boundary
When speaking of parts and
sub-systems it is patent that some conception of the
separateness of things exists. This leads to the idea of
boundary. Without a defining of boundary it is impossible to
speak at all coherently of the system or these
sub-systems. The location of boundary is, therefore,
fundamental to the relating of systems to each other. As
Elizabeth Richardson says, whether looking at the individual,
the group or the institution, we must be concerned with
defining boundaries “because it helps us to examine
independence and interdependence.” (THE TEACHER, THE SCHOOL
AND THE TASK OF MANAGEMENT)
Environment
Outside the boundary is the
environment of the system, and there will be, at least in the
case of ‘open’ systems, an interaction between the two. As
Hodge points out, educational systems are open ones. In fact,
such systems have to exchange materials with their
environments in order to survive; “they exist only if they
take in raw materials, convert these into useful products and
export the products back into society.” The task of an
institution is the “import - conversion – export process” and
in an attempt to define the task, the boundary has to be
identified through which “the raw materials are imported at
one end and the finished product at the other.” (Elizabeth
Richardson). A critical look at their own institution by staff
will quite likely lead them to consider “whether the
boundaries that separate out the different parts of the
institution have been drawn in the right places” - if not,
“leaders” are ostensible, lacking real authority to control
boundaries. For example, over time, certain leadership roles
may have lost meaning. In a percipient section on leadership
as a boundary function, Richardson writes of control as
involving the exercise of enabling and inhibiting powers,
since some activities are to be promoted and others
suppressed. An illuminating concept of a double boundary is
now developed, within which region the “discrimination powers
of leadership can operate, thus regulating the way in which
the internal world of the person, the group or the institution
is related to its environment and thus to other persons, other
groups and other institutions.” This factor of control, takes
on an added significance when differentiating between system
and environment in cases where the boundary is not clear.
Those activities that are beyond the control of management can
be classed as system environment.
Open and Closed Systems
It is axiomatic to speak of all
systems having boundaries. A closed system is self-contained
and is capable of having a clear boundary placed around it. It
has an environment but lacks interaction with it. The open
system, on the other hand, “continually gives up matter to the
outer world and takes in matter from it, but which maintains
itself in this continuous exchange in a steady state...” (BANGHART).
Educational institutions are embraced by this definition. For
one thing they are generally complex and their boundaries do
not appear clear or finite. Despite difficulties of boundary
definition, provided feasible and sensible boundaries can be
agreed upon, understanding will be enhanced and meaningful
activities may be undertaken within the organisation by those
working in it. Immegart and Pilecki observe that the
alteration of system boundaries is possible to enhance system
development while on the individual level, a person will find
it easier to readjust within a system, than to cross the
boundary for purposes of entering or leaving it.
A helpful distinction between
two kinds of environment is made by the same two authors.
Stressing the crucial importance of environment – its power to
affect the system, particularly open systems, they write of
the proximal environment, or that of which the system is aware
and the distal, that of which the system is unaware. This has
much implication for educational systems: as open systems they
must extend their awareness of environment since forces there
have the power to affect the system and its activities. It
follows, therefore, that on-going educational institutions
will seek continually to enlarge the proximal environment and
conversely will endeavour to reduce the distal; “extensive and
intensive knowledge of the environment is crucial.”
Educational institutions are ultimately judged by their
service to the larger environment; the conclusion reached,
therefore, is valuable: where systems contribute to and
enhance their environment, the environment will reward and
enhance the system. A further helpful comment on the concept
of environment is made by J. L. Davies in his article “The
Refinement of the Conceptual Framework of Output Measurement”
where he speaks of the substantive (groups with a special
interest in the organisation) and the general environment
(public opinion at large). The community, therefore, can
provide, expect, criticise and assess and these activities may
be shown to be inter-related in a cyclical process.
The concepts of boundary and
environment have been considered at some length because I
believe they are of crucial importance in any
conceptualisation of a situation. Where a system begins and
ends is difficult of determination in educational contexts but
it must be done if the conceptualisation is to be meaningful.
The corollary is that an educational systems environment is
also not always clear but the attempt to clarify is one
of the purposes of this exercise. The main difficulties in
conceptualising an educational situation lie here (closely
followed by determination of output!) In the first place,
there can be a duality of conception. For example, one may
speak of the professional system overall in which one works;
then clearly there is the concept of one’s particular work
situation. Both I believe are necessary if the full
implications of the input – output relationship are to be
realised.
SYSTEMS – ITS DATA
Systems
Theory – it seems to me, is of
value if all it did was to provoke thought about one’s work
situation. This, of course, is the basic position but then
from here many fruitful approaches, I believe, emanate
concerned with the optimising of the potentials of the
specific organisation. Immegart and Pilecki succinctly
describe the essence of the systems movement as a “mode of
thought”, that is “systematic and relational”. Further
characteristics of the systems movement are delineated:
thought is concerned with events in context and on their
evolutionary aspects: consequently structures are seen in
their relationships and connections: its approach is
essentially practical and operational and at the same time
looks to the future; it is realistic for it is concerned with
such as costs, gains and alternatives; it is eclectic and,
therefore, acts as a unifying force across disciplines; it is
“a useful perspective on reality” – an apposite summing-up!
Hodge is somewhat more mundane
in his definition: it is an approach “whereby thorough
analysis of a system may be undertaken.” Analysis is followed
by synthesis of old and new elements, models to predict the
effectiveness of the system follow, and finally, simulation,
prior to implementation. It is useful here to consider types
of system, a subject touched on in the first section. A. J.
Romiszowski refers to two basic types: deterministic and
probabilistic. In connection with the latter he speaks of
their being either simple (i.e. having few elements or
inter-relationships) or complex (i.e. having many elements or
inter-relationships) – but this is a use of the word I have
tried to refine in Section 1. The terms open and closed as a
further classification of systems have already been discussed.
In this paper the educational organisation is regarded as open
and probabilistic. Open systems consist of the following
elements:
a)
inputs of energy
b)
process components
c)
outputs of energy
d)
a control mechanism
(the comparator).
Properties of Systems
In addition, all systems, open
and closed, possess certain well-known properties, some of
which were mentioned earlier in the paper; others of
particular significance are the factors known as variables and
parameters and the possession of sub-systems. Ideally, the
open system is self regulating; this state is achieved by the
above mentioned comparator (or error signal generator as Hodge
calls it), which provides the vital function of feeding back
information and/or energy from its output to its input. This
relay of information, termed feedback may be positive
(i.e. supportive to the status quo) or negative (i.e.
challenging); it may also be either internal (coming from the
system’s processes themselves) or external (coming from the
system’s environment). It may be formal (from devised
channels) or informal (not conforming to prescribed
arrangements). An open system operating as above would be an
adaptive one, that is, adjusting to changes in the environment
– in the terminology it would possess equilibrium and
homeostasis. The obverse of this condition is known as entropy
and here an interesting point is made by Hodge where he states
(following others) that the entropy of physical systems tends
to increase over time while with behavioural (or human)
systems the more complex the system becomes, the less random
is the distribution of energy.
Approaches
Four approaches to the concept
of systems are listed by Immegart:
1.
Theories of the
whole.
2.
Process theories.
3.
Theories of system
properties.
4.
Output theories.
Process
theory is concerned with “focus
on the processing of inputs through sub-systems into system
output”; theories of system properties are derived from “the
recurring properties and states evinced in the life-space of a
wide variety of systems”; output theories focus on the
“products of system action relative to their impact on the
system and/or its environment.”
Of these four
approaches, process theory is the one of most central concern
to this paper. The input – output relationship is the essence
of systems theories and process theory is the term applied to
this particular concept. Inputs to a system are processed,
altered or modified by passage through sub-systems; what has
been acted on by the system is now an output and the effect of
this on subsequent input is seen in terms of
feedback.
Feedback
The terms “operands” (the
processed) and “operators” (the processors) comprise inputs;
output can be “productive” (tangible or substantive), and
“affective” (intangible, the feelings or reactions of people.)
The processing system may in fact be a number or combination
of several sub-systems so that each processing sub-system
becomes and input-output system in its own right – that is,
one system output becomes system input for a new sub-system.
Feedback, an output phenomenon, in both its external and
internal form then affects future system action. The concept
of feedback is discussed illuminatingly by Buckley when
speaking of open systems, whose:
i) characteristic
features depend on certain internal parameters or criterion
variables remaining within certain limits.
ii) organisation
has developed a selective sensitivity, or mapped relationship,
to environmental things.
iii) sensory
apparatus is able to distinguish any deviations of the
systems’ internal states from goal-states defined in terms of
the criterion variables.
iv) such
that feedback of this ‘mismatch’ information into the system’s
behaviour-directing centres reduces (in the case of negative
feedback) or increases (positive feedback) the deviation of
the system from its goal-states or criterion limits.
(Buckley,
W.: Sociology and modern systems theory)
Feedback –
controlled systems are referred to as goal-directed and
not merely goal-oriented, claims Buckley, since it is
the deviations from the goal state itself that direct the
behaviour of the system, rather than some predetermined
internal mechanism that aims blindly. For effective
self-direction a socio-cultural system must receive a full
flow of three kinds of information:
i)
from the world
outside.
ii)
from the past, with
a wide range of recall.
iii)
about itself
and its own parts.
These types of
information are used by three kinds of feedback:
1)
goal-seeking
– feedback of new external data into the system…whose
operational channels remain unchanged;
2)
learning –
feedback of new external data for the changing of these
operating channels themselves, i.e. a change in the
structure of the system;
3)
consciousness,
or self-awareness, feedback of new internal data via
secondary messages about changes in the state of the system
itself.
Higher-order
feedback nets facilitate four higher orders of purposes:
1)
seeking of
immediate satisfaction,
2)
self-preservation,
3)
preservation of the
group,
4)
preservation of a
process of goal-seeking beyond any one group.
Theories of
system properties contend all
open systems exhibit identical properties, whereby systems can
be analysed. These properties can be assessed in a number of
ways relative to a particular type of system.
Finally
output theories or output analysis is concerned with the
following:
i) productivity
(attainment of organisational goals);
ii) organisational
health (dynamic interaction of the organisation and its
environment);
iii) integration
potential (meshing the needs of individuals and groups within
the organisation to organisational goals).
A cautionary
note is sounded by Immegart and Pilecki with reference to open
systems in the educational context: just because a system,
such as a school, is characterised as open does not mean the
system is or will remain “maximally functional dynamic or
contributing”: conscious effort on the part of the system to
maximise both its existence and its relationship to its
environment is needed. It follows that the administrator must
view himself personally as an open system; more important is
not the being well-trained, able, etc., but rather being
“vital, relevant and functionally contributing”. (BUCKLEY)
Sub-Systems
As an integral element of
conceptualisation is the location of sub-systems this topic
concludes this section. Basically all systems have sub-systems
and all systems have supra-systems; the boundaries, it is
acknowledged, tend to be arbitrary but the importance of the
concept is that system action is the result of the functional
interplay of sub-systems; in addition sub-systems are a useful
point of focus for attending to system malfunctions.
Sub-systems, therefore, must be related to each other and to
the total system, in real and productive ways. Speaking of
schools, it follows that as they are not independent, they are
and need to be functionally relevant to other sub-systems of
the community and nation; “to yield maximal results, schools
need to contribute as sub-systems to each of their
supra-systems.” (BUCKLEY)
SYSTEMS THEORY AND EDUCATION
Fundamentally, general systems
theory is the basis for studying phenomena from many kinds of
systems. From this confluence of ideas comes perhaps our best
hope of a common language. This theory considers educational
institutions as sub-systems operating within an environment
and tries to apply the systems approach to problems wherever
they are, seeking by the potentiality of the common language
to investigate all ramifications from all possible angles.
Systems thinking is concerned with “fixing objectives,
selecting appropriate means of achieving them, devising action
programmes, assessing their impact and revising the process in
the light of experience.” As Birley says, educators are in
need of such a tool for their basic function of educating (and
of planning education). Systems thought provides a coherent
context in order to focus on values. (BIRLEY, D: PLANNING AND
EDUCATION)
System Regulation and Maintenance
Knowledge of systems theory
gives the administrator an insight into the importance of
involving the community (being receptive to external forces)
in order to regulate and maintain itself in a desired “steady
state”. The achievement of homeostasis is tied in with the
concepts of information and communication because it is
through these (their transmission and processing) that system
threats or imbalances are acted on. Related to this is the
importance of gaining purposive and evaluative feedback about
the system; constant attention should be given to the need for
this and formal feedback channels should be developed.
Negative, or critical feedback, rather than positive or
re-enforcing, is seen to be necessary for open system
survival. One particular type of feedback, proportional, where
the quantity of evaluative information is controlled
proportionate to system needs would, to the administrator, be
the most satisfactory type. In schools, internal feedback is
needed between administration and teachers as well as external
feedback between the school (or other institution) and the
community, including the L.E.A. Balance between positive and
negative feedback from relevant sources is also needed.
Overload must be avoided.
System Dynamics and Change
Systems
thought leads the educationalist to a realisation of the
importance of choosing to grow (or degenerate) – and hence
achieving a steady state in the face of entropic tendencies
and external pressures. He must maximise the school’s (or
college’s) relationship with its environment to obtain the
resources for change and for dynamic evolution.
System Decline
System
impingements that contribute to system decline are of two
general kinds. Internal threats (system decay) cause the
deterioration of the component of a system, while external
threats (system disturbances) move a system from one state to
another. The administrator in such cases must be able to deal
precisely with what is affecting the system’s life state –
stress must be recognised and avoided. If a system must devote
all its efforts to prevention of decline and breakdown,
“little will be left for system adaptation and growth.” (BIRLEY)
Some first
principles of the relevance of systems for administrators
follow.
Administration
is a system in and of itself. Practically, the administrative
system “replenishes itself by selecting new or replacement
members (input) and orients the new administrators to the
system (via system processes); the new members of the
administrative staff then affect the administrative system per
se as well as the larger organisation context of which it is a
part.”
The
administrative system is actually a sub-system of a larger
organisation system and is a supra-system to
sub-administrative systems. Practically, “administration does
not exist in isolation; rather it is functionally related and
necessarily contributory to a larger context (system)” – the
L.E.A. (birley)
The
administrative system, being an open system, draws on its
environment (e.g. for replacement members) and its outputs
affect the environment. Therefore, the administrative system
is a performance system functionally related to larger
contexts (the total organisation and the environment).
Practically,
“it is in essence an exchange system that processes wanted
goods and services.”
Administrative
systems must be concerned with more than the processing of
work as the sole outcomes of system activity. There are other
categories of system outcomes: integration, health and
feedback. Systems must realise more than productivity.
Practically, only an organisation can “optimise this full
range of outcomes can they maximise their basic contributions
to their clients (students) and environment.”
Conscious and
rational planning is needed for system optimisation. It is a
notion of systems that output may exceed input, but generally,
in practice, output “approximates input in a somewhat lesser
quantity.”
Other
important implications for administrative practice are:
objective consideration of resources is necessary in
formulating system strategy and action; attracting energy and
resources, maintaining them and rejuvenating them as necessary
are “crucial challenges” for any administrator; monitor and
control mechanisms do not necessarily limit system action but
rather set “appropriate boundaries for action and help the
system to avoid pitfalls and impediments revealed in past
action”; by means of the homeostatic mechanism “differences
are resolved and system efforts (of teachers and
administrators) are co-ordinated for action toward basic
organisational goals”; systems ideas indicate a need for a
communications structure that “maximally permits the exchange
of necessary information in an organization and also provides
for information flow in all directions – up, down and
horizontally,”; if an open system does not seek “consciously
a dynamic existence, if left to the natural tendency of all
systems, it will become increasingly useless.” It is pointed
out that schools having a captive clientele would probably
never become entirely entropic but clearly this does not apply
to the sphere of adult education, where the students attend
voluntarily.
OUTPUT IDENTIFICATION
Output identification is crucial to
systems thought but is generally difficult to make clear.
Birley succinctly states the dilemma: “unless the education
service takes seriously the question of measuring its own
performance it will never be able to make out a satisfactory
case for the resources it needs, nor use to the full the
resources it is given.” The problem, of course, is to isolate
educational output and at the same time to evaluate it. This,
I believe, is given an added dimension of difficulty in the
field of Adult Education.
