"[[Michael Kami]] refers to this team approach as concurrent, as opposed to assembly-line manufacturing, in which responsibility for one part of the process is handed off in stages to the next in line. A concurrent approach brings all participants together at the beginning of the design phase. As Dr. Kami points out, **only about 10 percent of a product’s costs are incurred during the design phase, but 90 percent of the costs are irrevocably committed**."
