Moderate To Extreme Cost Sensitivity
- Most designers will say they're worried about cost -- but what
       they mean by that varies substantially
  - Component cost is most visible to designers -- but is
       sometimes the wrong thing to optimize for (discussed
Design Challenges:
  - Variable "cushion factor" to handle different requirements
       for cost vs. product robustness with same component
  - Life-cycle cost optimization (more on this later)
