Given is a PERT project network diagram as shown below. Start D Activity Start ABCDEFGH End Time 0 1.35 3.65 4.327 .36 8.25 1.394 .68 3.250 a) The Project Completion time = (in 2 decimal places) b) The Earliest Start time, Es, of Activity G- (in 2 decimal places) c) The Latest Finish time, LF, of Acitivity C (in 2 decimal places) d) The critical activities are (ex. type in critical activities as ABCD no comma, no space)

CPM refers to critical path method where shortest path is taken to plan the project. The steps in CPM schedule include: -

• Individual activities are specified.
• Sequence of those activities are determined.
• Drawing a network diagram.
• Completion time of each activity is estimated.
• Critical path is identified.
• CPM diagram is updated.
