28
Q

What is technology-push products?

A

Firm begins with new technology and looks for market. Ex goretex rain wear.

29
Q

What is platform products?

A

built around a prexisting technological subsytem: consumer electronics, printers computers

30
Q

what is process intensive products?

31
Q

What is customized products?

A

new products that are a slight variations of existing products. ex motors swithces batteries

32
Q

what is high risk products?

A

techincal or market uncertainities create high risks of failure. Ex pharemecuticals, space systems.

33
Q

What is quick bulid products?

A

rapid modeling and prototyping enables many desing build test cycles. Software, celluar phones.

34
Q

What is value analysis/ value engineering?

A

the purpose is to simplify products and processes. objective is to acheive better performance at a lower cost while maintaining all funictioanl requirments defined by customer.

35
Q

what are the two apporaches of designing products for manufcature and assembly?
