1. Safety – is the product safe to use/construct?2. Reliability – will it work consistently over time?3. Cost – is it affordable?4. Quality Control – does it meet customer requirements?5. 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. 3-minute maximum. Teacher will ask questions. IOT
