• process control using CUSUM
• the concept of a standard process o experimental strategy in relation to one key emphasis of Taguchi.

A main theme is the relation of these technologies to the product life span and to several other quality technologies of current interest. It is timely to take advantage of the opportunities to cross-fertilize recent quality technology advances occurring in the automotive and the process industries.
