1. With 1 partner:1. Select a technological system, and 2. Determine the 5 components of that

technological system (i.e., Goals, Inputs, Process, Outputs, Feedback and Control).

Components:– Goals

• Humans develop technology to meet needs• Each artifact meets more than one goal

– Inputs • Resources that go into a system and are used by it

– Processes• Design Process, Production Process, Mgt. Process

– Outputs• Technological systems are designed to produce specific outputs. • Manufactured products, constructed structures, communicated

messages, transported people or goods.– Feedback and Control

• Using information about the outputs to regulate the system.

INPUTS• Resources that go into technology:

– People – planners, designers, builders, testers, administration, investors, etc.

– Information – math, science, and technical principles, etc.– Time – to plan, design, make, market, ship, etc. – Capital – $ for employees, materials, marketing, etc.– Machines and tools – manufacturing facilities, etc.– Materials – natural, synthetic, composite– Energy – to design, construct, ship, etc.

PROCESSES• Management

– Planning and scheduling– Organizing (e.g., salaries)– Actuating (e.g., marketing)– Controlling

• Design– Engineering Design Process– Problem Solving Process

• Production– Communication– Construction– Energy and Power– Manufacturing– Transportation

• Used to regulate and control a technological system• Designs need to be continually checked and

critiqued, refined and improved• Risk analysis is used to minimize the likelihood of

undesired outputs• Feedback in the form of:

– Performance testing– Testing and evaluation– Surveys– Sales results– Quality control (actual operation vs. intended operation)

Classwork / Homework• Select a technological system not yet

mentioned in this course, • Sketch 3-view diagrams of it in detail

(include approximate dimensions), • Describe in detail the 5 components of

that technological system (Goals, Inputs, Process, Outputs, Feedback and Control).
