1.1. Write a generalized view of the evolution of concurrent engineering and product design, in terms of increasing product performance, reducing cost through DFM/DFA/ESI or increasing quality and variability reduction through DoE and Six Sigma. Give an example of products from your own personal experience, or compare and contrast two different companies such as Motorola versus GE or Dell versus HP in quality and cost. You may also choose any other product family such as printers, TVs, computer displays, TV recorders, cell phones, autos, and computers (desktops, laptops, or tablets), and trace their evolution in performance, cost and quality, using the tools mentioned in Chap. 1.
