Title: Introduction to Engineering and Technology Concepts


1
Introduction to Engineering and Technology
Concepts
  • Unit One
  • Chapter Two Technology as a System

2
Instructions for Success
  • Each chapter of every unit will begin with a
    Mindjog. This is a warm up question that you
    should answer in your workbook in the proper
    chapter.
  • Please take notes as you move through the
    presentations in the notebook that has been
    provided.
  • Sections will come up in each presentation with
    an assignment notice. Turn to the section
    detailed on the slide in your workbook and
    complete the assignment before proceeding.
  • Good luck!

3
Objective
  • Students will define the systems model,
    recognizing that systems-thinking applies logic
    and creativity.

4
Mindjog!
  • On your worksheet, please respond to the
    following question 
  • Pick a piece of technology that you use
    everyday. Now think of how you could make it
    better. Write a concrete goal statement,
    explaining the purpose of your addition and how
    it benefits the original product.

5
The First Piece of Technology
  • When considering the development of a piece of
    technology, one goes through a systematic,
    iterative, approach.
  • That is, finding a solution to a problem involves
    a repeated method that follows procedure.
  • The problem solving method is one approach to
    this development process.

6
The System
  • What is the definition of a system?
  • System a group of parts working together in a
    predictable way, designed to achieve a goal
    (Wright, 2004).
  • Consider the development of technology in this
    example Our ancestors may have wanted to open a
    coconut for food. When they could not force it
    open with their bare hands, they began to think
    of what else could work. Thus began the
    development of a hammer.

7
The System Components
  • All technological systems are made up of several
    components. They include
  • Goals
  • Inputs
  • Processes
  • Outputs
  • Feedback and Control (Wright, 2004)

8
Goals
  • Technology is invented with a goal, or goals, in
    mind.
  • Goal the desire to meet a need (Wright, 2004).
  • Also, understand that completed artifacts can
    accomplish more than one goal.
  • One persons goal may be developing a way to get
    people to and from, while also making money. An
    automobile accomplishes both of these things
    (Wright, 2004).

9
Inputs
  • Inputs any resource that go into the system and
    are used by the system.
  • Technology systems have at least seven inputs
  • People
  • Materials
  • Tools and Machines
  • Energy
  • Information
  • Finances
  • Time (Wright, 2004)

10
Inputs (continued)
  • Consider that people are the most important input
    to the system. Without people there would be no
    technology.
  • Materials are the substances that make up an
    artifact.
  • Tools and machines extend and speed up the
    development process.
  • Energy is the ability to do any kind of work.
  • Information is collected and organized data.
  • Finances are the monetary support of the economy
    (Wright, 2004).

11
Processes
  • All technological systems are characterized by
    some sort of action.
  • The steps in these actions are called a process.
  • Tech systems use three types of processes
  • Problem solving, production, and management
    processes (Wright, 2004).

12
Processes (continued)
  • The problem solving process is similar to the
    scientific method and can be broken down into
    steps
  • Identifying a problem
  • Developing potential solutions
  • Isolating, refining, and detailing the best
    solution
  • Modeling/testing and evaluating the solution
  • Communicating the final solution (Wright, 2004).

13
Processes (continued)
  • The production process are the actions that are
    completed to perform the function of the
    technological system.
  • This can be something as basic as a set of
    instructions to complete a specific task, like
    building something (Wright, 2004).

14
Processes (continued)
  • The management process are all of the actions
    people use to ensure that the production
    processes operates efficiently and appropriately.
  • Management uses four basic steps
  • Planning setting goals and different courses of
    action
  • Organizing diving tasks into segments
  • Actuating assigning and supervising work
  • Controlling comparing system output to the goal
    (Wright, 2004)

15
Outputs
  • Outputs can include manufactured products,
    constructed structures, communicated messages, or
    transported people or goods.
  • These are designed outputs.
  • Consider that there is also an output that is
    known as scrap.
  • Scrap can be leftovers waste, pollution,
    congestion, and so on (Wright, 2004).

16
Feedback/Control
  • All systems have feedback and control.
  • This process involves using information gathered
    from the outputs to regulate the system.
  • Negative feedback could call for adjustments to
    the process.
  • Positive feedback pushes towards meeting the goal
    that began the technological system (Wright,
    2004).

17
The System Model
  • Consider this graphical representation of a
    technological system.

Feedback/Control

Assignment 1
  • Please turn to the section in your workbook
    entitled, Unit 1, Chapter Two Technology as a
    System.
  • Complete the extension questions under the
    Assignment 1 header before moving onto the
    next section of slides.

19
BEFORE MOVING ON
  • Did you complete the Assignment 1 Section
    under the Unit 1, Chapter Two Technology as a
    System section of your workbook?
  • If you have, please proceed to the next slide.

20
Unit Two Completed!
  • Please close this presentation and launch the
    file entitled, Chapter 3 Types of
    Technological Systems.
