Question 1 Find the critical path using the critical path method for activities shown in Table 1. Correctly represent the network diagram with activity name, early start (ES), early finish (EF), late start (LS), late finish (LF), and duration. See Figure 1 for legend) and precedence relationships (arrows from/to activities). In answering this question, if you need to make any assumptions in addition to the information provided to you, you need to EXPLICITLY state them. Problem assumption: Start date is 0 for forward pass.

Is there any impact on the project duration? 1.5 How much longer duration C can take without any impact on the total project duration?
