Consider Table 6-3. All duration estimates or estimated times are in weeks, and the network

proceeds from Node 1 to Node 8. (Note that you can easily change this table to create

multiple exercises.)

  Draw an AOA network diagram representing the project. Put the node numbers in circles

and draw arrows from node to node, labeling each arrow with the activity letter and

estimated time.

  Identify all of the paths on the network diagram and note how long they are, using Figure 6-8

as a guide for how to represent each path.

.  What is the critical path for this project and how long is it?

 What is the shortest possible time needed to complete this project?
