What is a System?
A set of interrelated components With a clearly defined boundary Working together To achieve a common set of objectives ... By accepting inputs and producing
output In an organized transformation process

Basic Functions of a System
Input– Capturing and assembling elements that enter the
system to be processed Processing
– Transformation process that converts input into output
Output– Transferring transformed elements to their
ultimate destination

Cybernetic System
All systems have input, processing, and output A cybernetic system, a self-monitoring, self-
regulating system, adds feedback and control:– Feedback is data about the performance of a
system– Control involves monitoring and evaluating
feedback to determine whether a system is moving toward the achievement of its goal

If a system is one of the components of a larger system, it is a subsystem– The larger system is an environment
Several systems may share the same environment– Some may be connected via a shared
boundary, or interface
