What can be said in conclusion?
Robust design is designing a way to make the final product consistent when the process is subject to a variety of "noise". This can be done through a variety of experimentation methods. The results are capable of showing how to develop a product/process that will be robust. The advantages of robust design are that the products are of good quality, cheaper, and more customer friendly than their non-robust counterparts. Although there are disadvantages, having a robust product design can give companies a large competitive edge.
