MODULO 3.
A system is a group of parts
working together to
accomplish a task.
Confused?
Read the following article: WHAT IS A SYSTEM?
Make a summary of the following aspects:
1. Definition
2. Characteristics
3. Types
First, some vocabulary
you need to know..
System: a set of things working together as a
mechanism or interconnecting network.
Which of the examples is not a system?
Subsystem: a self-contained system in a larger
system.
Organize the following sub-systems:
Dgisitvee, Bkare, Itnefrcae
A
B
C
Input: what is put in, taken in, or operated on by a
process or system.
Find the input of
the following
examples:
Output: something produced by a person,
machine, or industry; supplied by a device or
system.
What are these outputs?
Feedback: the modification or control of a
process or system because of its results or effects.
**Give feedback to your partners.**
Purpose/Objective: the reason to do something.
What is your
objective for
studying at SENA?
Achievement: Accomplish by effort, skill, or
courage.
What has been your greatest
achievement in life?
ACTIVITY 1.
Fill the blanks with the correct words from the box:
ACTIVITY 1:
UNIVERSAL SYSTEMS MODEL
PURPOSE/OBJECTIVE
What you want
the system to do
INPUT
Resources that go
into the system
PROCESS
Steps that lead to a
result
OUTPUT
The result that comes
out of the system
FEEDBACK
Comparing the results to the objective, the
adjustments are made to the inputs and/or process
So, these are the elements to have a
Universal System Model:

c. Draw the USM (Universal System Model)
Including all the aspects identified in the previous
analysis:
*** Remember to include ALL the aspects of a SYSTEM. *****
Write POSITIVE AND NEGATIVE effects for the OUTPUT and FEEDBACK.
