Figure 4.5.5_3 shows a slightly different approach from the approach in

Figure 4.5.5_1. In this approach, rather than using two processes to make

each part, the part C detail has been re-designed to call out a different

manufacturing process. Thus, not all parts have the same tolerance. This

approach could be used to take advantage of a supplier with good process

capability while giving the other supplier(s) some relief, and still meet the

assembly level requirements.
