Task 2.1 Study the Four Process Flow Diagrams

These are on the following page, labelled PFD-1 through PFD-4.  Look first at PFD-1, which illustrates the processes and linkages for building the three drills:  DR12, DR54, and DR11.  That suggests that the three drill models, though they may have different features, generally follow the same work steps.  Next, On PFD-2 for orbital sanders OS31 and OS32, start at the final process “Pack” and look upstream:  identical through “Test” and “Final Assembly”, with one difference above.  Continue to study PFD-3 and PFD-4, looking for commonalities and differences.
