  1. RspGF=”font-family:’Arial’;font-size:10pt;”(TCOs 3, 5, and 6) What is the difference between the concepts of design quality and conformance quality? (Points : 30)
Design quality is the inherent value of the product in the  marketplace. It refers to the specifications of quality (performance,, features, reliability, serviceability, aesthetics, perceived quality) which are brought up from the product design process.

  1. RspGF=”font-family:’Arial’;font-size:10pt;”(TCOs 4, 6, and 7) Distinguish between dependent and independent demand. How are these demands treated differently? (Points : 30)
Independent demand is the demands for various items which are unrelated to each other. In other words, independent is demand for a finished product such as  a computer, a bicycle. On the other hand, dependent demand is demand for component parts, or a need for an item is directly related to the need for some other items such as the microchips in a computer, or the wheels of a bicycle.
Dependent demand is simply computed, whereas independent demand is uncertain, extra units need to be stored.
