An engineering driven design is based on the premise that the engineering designer can specify any
tolerance values deemed necessary to ensure the perceived functional requirements of a product.

process driven design

A process driven design establishes the dimensional tolerances that are placed on a drawing based
entirely on the capability of the manufacturing process, not on the requirements of the fit and function
between mating parts.

inspection driven design

An inspection driven design derives dimensional tolerances from the expected measurement technique and equipment that will be used to inspect the manufactured parts. Inspection driven design does not use the functional limits as the assigned values for the tolerances that are placed on the drawing.
