System theory: is the interdisciplinary study of system
General System Theory is a general science of “wholeness”
Every system is bounded by space and time, influenced by its environment, defined by its structure and purpose, and expressed through its functioning
System may be more than the sum of its part
The parts rely on one another, are interrelated, share a common purpose, and together form a whole.
Purpose of generalsystemtheory: We seek some way of ordering what we encounter to avoid being overloaded with information.
A system is ever-changing and nay change in one part affects the whole
Input: information that enters the system
Feedback: process through which the output is returned to the system
Input: The energy & raw material transformed by the system
Throughput: The process used by the system to convert raw
materials or energy from the environment into products by either the system itself or the environment
Output: The product or service which results from the systems
Feedback: can be used to evaluate & monitor the system & to guide it to more effective performance.
Subsystem: A system which is a part of a larger system.
dynamic/active system: Interact in behavior and processes
dynamic/active system:
hava changes
Dynamic/active system: (A healthy young adult grows more independent, interdependent, &s self-directed in response to stimuli from peers, family, school, work, and recreational activities.)
passive/static system
Being processed and no changes
Closed systems: Fixed, automatic relationships
Closed systems: no give or take or interaction with the environment
Open systems: Interacts with the environment
Boundary:The line or point where a system or subsystem can be differentiated from its environment or from other subsystems.
Goal: The overall purpose for existence or the desired outcomes.
Entropy: The tendency for a system to develop order & energy over time.
Negentropy:The tendency of a system to lose energy & dissolve into chaos.
Control or Cybernation: make Corrections.
Equifinality: Objectives can be achieved with varying inputs & in different ways
An open system and its environment are highly interrelated
Achange on only one of the elements must produce change in all the others.
All systems tend toward equilibrium, which is a balance of various forces within and outside of a system.
To be visible, a system must be strongly goal-directed, governed by feedback, and have the ability to adapt to changing circumstances.
general system theory: focus on stability rather than the change
KURTLEWINS: Change Theory
change theory: “a dynamic balance of forces working in opposing directions”
change theory: “a comprehensive description and illustration of how and why a desired change is expected to happen in a particular context.”
DRIVING FORCES: those that push in a direction that causes change
Driving forces: They cause a shift in the equilibrium towards change.
RESTRAINING FORCES: hinder change because they push the patient in the opposite direction.
RESTRAINING FORCES: They cause shifts in the equilibrium that opposes change.
