Dimensional Management (DM) is an engineering methodology combined with computer simulation tools used to improve quality and reduce cost through controlled variation and robust design. It is applied throughout the Product Development Cycle. DM consists of six (6) steps and fourteen (14) associated deliverables. The steps will be discussed in the first section while the deliverables will be covered in another section of this class.
