What Is A System?
Systems have three basic functions:
1. Input:
Involves capturing and assembling
elements that enter the system to be
processed.
Example: - raw materials,
- energy,
- data.
What Is A System? (continued)
Systems have three basic functions (continued):
2. Processing:
involves transformation processes that convert input
into output.
Example: - manufacturing process,
3. Output:
involves transferring elements that have been
produced by a transformation process to their
ultimate destination.
Example: - finished products,
- human services
