Today I'm going to challenge you with a slightly unusual Network Diagram problem. Most PMP exam prep materials I have seen use Finish-to-Start relationships on the Network Diagram. In this article, you are going to see a Network Diagram with a Finish-to-Finish relationship. What? Yes, that's right, Finish-to-Finish. So, bring your pen and paper and get ready to solve this problem.
Note: In all likelihood, this problem is beyond the scope of the PMP exam. But if you are an adventurous type, go ahead and take the plunge. We'll have fun.
Refer to the Network Diagram below and answer the questions following it:
- Identify the Critical Path of the network.
- What is the duration of the Critical Path?
- Calculate the Early Start (ES), Early Finish (EF), Late Start (LS) and Late Finish (LF) for each activity on the Network Diagram.
- Calculate the Total Float (TF) and Free Float (FF) for each activity on the Network Diagram.
- If the duration of activity E is changed to 9 days, how will it impact the critical path?
- If the duration of activity F is changed to 8 days (with activity E's duration kept at the original value), how will it impact the critical path?
