Some Help with few questions on quality engineering

What are the typical sources of out-of-tolerance variance in component manufacturing
processes? Classify the sources into 'common' and 'special' causes.

Discuss how cost models generally account for quality costs and in relation to the
iceberg diagram how do these models differ from the true impact of poor quality.

Why in product development does the application of techniques DFM/A enable
businesses to make major reductions in time-to-market?

How can an organisation establish what the customer’s CTQs are? Give examples of
useful CTQs.

Just go through your lecture notes these are quite focused questions and im sure it will be in the teaching material,

but im just guessing here:
1) stuff like wearing of a press, components dont cure at the right temperature window...

2) no idea, maybe higher upfront tooling and manufacturing costs save money due to increased product quality ie therefore less waste & warranty

3) DFMEA, focus resources on issues with serious consequences if it their fault ie would it cause casualties.. or issues that will continually prop up, ie high probability of failure (its scored so spits out numbers)

4) no idea what a CTQ is, but ask them?
As Mnot says you should have lecture notes on this, DFMA is the design failure mode analysis, just think about it logically. The more testing and thinking you do about a product before it goes to market the less you will deal with people trying to return the product etc if it breaks, law suits etc.
