- Draw the network diagram (use activity on the node) 2) Explain how you determined the timing of activities and the total float. The Earliest Start time (EST) is 0 day for the first activity i.e. activity A in this case. For the following activities, EST is equal to Latest Finish Time (LFT) of the predecessor.
For example, EST of activity C is equal to LFT of its predecessors (activity B) = 9 days.
Earliest Finish Time (EFT) is calculated by adding duration to Earliest Start Time (EST).
Earliest Finish Time (EFT) = Earliest Start Time (EST) + Duration For example, EFT of activity C = EST (9 days) + duration (10 days) = 19 days ...
