3 why is it important to determine activity

Why is it important to determine the order of project activities? Discuss charts similar to network diagrams. Please explain those similarities and differences. The critical path to the project can not be determined unless the activity is sorted. Several different diagrams are similar to project network diagrams. For example, in traffic modeling, we try to find the shortest path between two points. However, in these figures, only one path is required. In the project network diagram, you need to complete all the activities to complete the project. How does the activity resource estimate affect the estimation activity period? The duration of the event depends on the resources allocated. For example, an event specialist should be able to complete in less time than a beginner. The amount of resources allocated to an activity also affects its estimated duration. Describe the difference between estimated time required for activities and estimated work required to execute activities. The workload estimate is related to the number of hours spent executing the activity. Activity period

The project network in Figure 17.8, which includes the start time and end time of all activities, highlights the previously identified critical path (1-2-3-4-6-7). Please note that in the activity on the critical path, the earliest start time is the same as the latest start time. This means that these activities on the critical path must be started on time and can not be delayed at all. If the start of the activity on the critical path is delayed, the whole project will take longer. In addition to simply checking the network, there is another way to determine the critical path. The activity on the critical path can be determined by examining which activity ES = LS or EF = LF. In Figure 17.8, since activities 1 to 2, 2 to 3, 3 to 4, 4 to 6, and 6 to 7 all have the same earliest start time and the latest start time (and EF = LF), the critical path It is on the top. on

The active time is calculated in the forward and reverse paths to determine the float. Estimate the completion time of the project The forward pass (early start + period = earliest exit) to calculate the earliest event time of the activity, for example, the earliest completion date of event F is 18 (14 + 4). In order to determine the activity in the critical path, the activity's latest activity time is calculated in the reverse direction (last end - duration = latest start) and the recent start date float of activity H is 20 (22 - 2). Total Float = Latest Complete - Earliest Start - Duration. For example, Activity C will fluctuate for 3 days (12 days - 6 days - 3 days).
