use the project network and the activity time estimates to determine the earliest st 5177498
Use the project network and the activity time estimates to determine the earliest start and earliest finish time for each activity by making a forward pass through the network. The earliest finish time for the last activity in the project identifies the total time required to complete the project. Use the project completion time identified in step 5 as the latest finish time for the last activity and make a backward pass through the network to identify the latest start and latest finish time for each activity. Use the difference between the latest start time and the earliest start time for each activity to determine the ctivity. The slack time can also be calculated by determining the difference between the latest finish time and the earliest finish time for each activity. Find the activities with zero slack; these are the critical activities (they lie on the critical path). These activities will have the same values for the earliest start and latest start. Additionally, they will have the same values for the earliest finish and latest finish. In other words, the values on the top of the top of the activity will be identical to the values on the bottom of the activity. Use the information from steps 5 and 6 to develop the activity schedule for the project. This will also involve the completion of the “master table” which includes all the values that pertain to each activity.
