Leveraging the Design Chain
In the product development process at most mid-sized and large companies, designs are defined in an engineering department and passed along in serial fashion (i.e., "thrown over the wall") to other design chain groups, each with an important perspective and insight into how the product should be configured. Manufacturing may find a faster, less costly way to fasten a housing to a frame, for example. Or marketing might want a more ergonomically contoured handle. Any suggested improvements or problems along the way send the design back to engineering.
