The Quality of product is something determined by the quality of Design and the Quality of Manufacture.
The Factor-of-ten cost increase Rule tell us that the cost of change in the design of a product increase 10 time in each phase of its development. Therefore, it is a good idea to design the product robust so that change during development and manufacturing will not be easy to make. This can best be achieved by concurrent Engineering and starting to think about quality during early stage of design.
If cost almost the same in resources to replace a customer than it does to remain one.
Draw and explian Deming's chain reaction on how improving quality improve competitiveness.
