Safety – is the product safe to use/construct?
Reliability – will it work consistently over time?
Cost – is it affordable?
Quality Control – does it meet customer requirements?
Environmental Concerns – does it harm the natural or
human environment negatively?
6. Manufacturability – can it be made?
7. Maintenance – how easily can it be maintained or upheld?
8. Ergonomics – how efficiently can the human body utilize it?

Classwork / Homework
1. Partner exercise - articles about particular
technology systems (i.e. Hubble, Maglev Train, etc.)
and students must:
1. Describe the system outputs – what are the
desired/undesired outputs?
2. Describe the operation of the system in terms of the 9 core
technologies.
2. Answers should be written up. 3 or 4 groups will be
chosen at random tomorrow to give presentation. 3minute maximum. Teacher will ask questions.
