Consider the table below, Network Diagram Data for a Small Project. All duration estimates or estimated times are in days; the network proceeds from Node 1 to Node 9.

1. 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. MS Powerpoint or Visio are good tools for this task.
2. Identify all of the parts on the network diagram and note how long they are, using the figure below as a guide for how to represent each path.
3. What is the critical path for this project and how long is it?
4. When is the earliest possible time that this project can be completed?
5. Enter the information into MS Project.

D =4 2 5 A = 1 E = 5 H = 6 B = 2 F = 4 J = 3 1 3 6 8 C = 3 1=2 7 G = 6 Note: Assume all durations are in days. Path 1: A-D-H-J Length = 1+4+6+3 = 14 days Path 2: B-E-H-J Length = 2+5+6+3 = 16 days Path 3: B-F-J Length = 2+4+3 = 9 days Path 4: C-G-I-J Length = 3+6+2+3 = 14 days Since the critical path is the longest path through the network diagram, Path 2, B-E-H-J, is the critical path for Project X.\f\f
