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? SystemSystem – 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 InputsInputs – 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. process.The steps in these actions are called a process. Tech systems use three types of processes:Tech systems use three types of processes: Problem solving, production, and management processes (Wright, 2004).Problem solving, production, and management processes (Wright, 2004).

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

13 Processes (continued) The are the actions that are completed to perform the function of the technological system.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).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 are all of the actions people use to ensure that the production processes operates efficiently and appropriately.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:Management uses four basic steps: Planning – setting goals and different courses of actionPlanning – setting goals and different courses of action Organizing – diving tasks into segmentsOrganizing – diving tasks into segments Actuating – assigning and supervising workActuating – assigning and supervising work Controlling – comparing system output to the goal (Wright, 2004)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.Outputs can include manufactured products, constructed structures, communicated messages, or transported people or goods. These are designed outputs.These are designed outputs. Consider that there is also an output that is known as scrap.Consider that there is also an output that is known as scrap. Scrap can be leftovers waste, pollution, congestion, and so on… (Wright, 2004).Scrap can be leftovers waste, pollution, congestion, and so on… (Wright, 2004).

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

18 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.
