Stages of Development

• 1. Concept Development
• Identifying customer needs
• Establishing design specs
• Concept generation selection

• 2. System-Level Design
• Product architecture
• Subsystems interface
• Industrial design
• Economics

Thinking towards the final

• Risk Reduction Prototype
• Innovate ? Generate neat concept
• Identify a risky component and TEST it.
• Experimentation ? improvement
• Expect to see this in the Analysis Testing
  portion of the final report.

Experimentation/Innovation

• Who ate the first egg?
• Where it comes from
• What it looks like
• Whats inside
• How did it catch on?
• Who would try it again?
• This is a good example of the innovation/experimen
  tation cycle
