QUESTIONS 12 THROUGH 15 REFER TO THE DIAGRAM IN FIGURE 2 AND THE TABLE...

25. The main difference between the two types (ADM, arrow diagramming

method, and PDM, precedence diagramming method) of the critical

path method (CPM) of scheduling is:

a. Placement of the activity on the logic diagram line.

b. Arrow diagramming method (ADM) is a deterministic method,

whereas the precedence diagramming method (PDM) is a probabi-

listic method.

c. Precedence diagramming method (PDM) is a deterministic method,

whereas the arrow diagramming method (ADM) is a probabilistic

method.

d. Precedence diagramming method (PDM) is a more accurate
