Precedence Diagrams

I really enjoyed this week's topic of precedence diagramming.  I learned how to do a forward pass and a backward pass to determine the slack/float of a project and how to determine the critical path of a project in an optimistic, most likely, or least likely time frame.  I used Microsoft Project to assist me with the WBS, AON and Gantt charts.  However, I did the precedence diagrams by hand as you can see, below.  I look forward to hearing from the professor to see if I arrived at the critical path and end dates correctly.
