WHAT IS A SYSTEM?
A system is defined as a set of interrelated components, with a clearly defined boundary, working together to achieve a common set of objectives by accepting inputs and producing outputs in an organized transformation process.
system have 3 basic functions:
- Input
- involves capturing and assembling elements that enter the system to be processed.
- Processing
- involves transformation processes that convert input into output.
- Output
- involves transferring elements that have been produced by a transformation
process to their ultimate destination.
CYBERNETIC SYSTEM
The system concept becomes even more useful by including two additional elements:
feedback and control. A system with feedback and control functions is sometimes
called a cybernetic system, that is, a self-monitoring, self-regulating system.
- Feedback - is data about performance of a system.
- Control - involves monitoring and evaluating feedback to determine whether a system is moving toward the achievement of its goal.
