Technology: The Human Made System

Essential Question How can we explain how a technology works?

Georgia Performance Standards MSENGR-TS-1a,b,c: The students will develop an understanding of the Universal Systems Model

Technology Is A Totally Human Entity Technology Is A Totally Human Entity. It is designed to benefit people, it has positive and negative impacts on the quality of human life, and its future is in the hands of human will.

Technology Is Systematic The various parts of technological activities work together in a predictable way to accomplish a common goal.

Technology As A System

WHAT IS A SYSTEM? A system is a group of parts that work together to achieve a goal.

Technological System INPUT PROCESS OUTPUT FEEDBACK

System Components

Systems have several major components which include: Goals Inputs Processes Outputs Feedback

GOALS Technology is designed to reach a desired goal. Most technology is designed with several goals in mind.

INPUTS Inputs are the elements that flow into the system and are consumed or processed by the system.

Input The command given to the system, it includes the:

INPUT Seven Resources of Technology People Information Materials Tools and Machines Energy Capital Time

PROCESS The process includes all of the activities that need to take place for the system to give the expected result.

Processes Processes are the steps needed to complete an identified task. Technology uses two major types of processes: Problem-Solving processes Transformation processes

Transformation processes include: Production processes Management processes

Production Processes Production processes are actions that create the physical solution to a problem or opportunity

Management Processes Functions of Management Planning – Developing goals and objectives Organizing - Structuring procedures to meet goals Actuating – Starting tasks Controlling – Checking results against goals

The result of the system OUTPUTS The result of the system

OUTPUT Output includes everything that results when the input and the process parts of the system go into effect. Outputs can be: Expected or unexpected

What are outputs? manufactured product constructed work communicated message transported person scrap and waste pollution

FEEDBACK Feedback is information about the outputs of a process or system that is used to regulate the system.

All Technological Systems Share Some Common Characteristics. They arise out of a human need. They are designed and developed by people They integrate resources to produce outputs They have consequences for people society, and the environment

They are evaluated by people In time, they are modified or abandoned.

Level of Development Obsolete Technology – Those that can no longer efficiently meet human needs for products and services Current Technology – Techniques used to produce most of the products and services today Emerging Technology – New technologies that are not widely employed today

FEEDBACK There are two different kinds of feedback: Positive/negative Desirable/undesirable

FORECASTING FOR THE FUTURE How can we determine what future technology or systems look like? Trends – something that is emerging as popular Surveys – a sample or collection of facts and figures Scenarios – an imagined set of events with details plans or possibilities Simulations – imitation or acting how something works
