4 Step Design Process1. Identify a Problem

2. Solution Design **Meets a human need**Use scientific principles

**Be suitable for use by more than one person.

A. Possible Solutions are compared.

B. Explain technology, using drawing/models.

C. Identify materials and estimate cost and development time.

D. List potential risks and benefits.

Lets look at a Possible Design Solution in Action!

3. Implementation Putting the plan into action-- ImplementationDevelop a Prototype

Performance Testing is a part of the Performance Testing is a part of the Implementation ProcessImplementation Process

4. Evaluation--

A. Does the Design Work?

B. How can the success of the design be measured?

C. Does the design solve the problem and meet people’s needs?

D. Have risks been minimized?

E. How can the design be improved?

F. What was learned that could help produce a better design?

New technology always has risks and benefits.

Benefits—way in which technology meets people’s needs.

Risks—harm or danger that the technology can cause people.
