The network diagram and schedule information provided in this task can be used to determine the critical path and calculate the duration of a project. A critical path is the longest sequence of activities that must be completed before a project can be finished. Knowing this information will help project managers identify which tasks are most important for ensuring that a project is completed on time. The schedule information provided contains both activity names, estimates for their durations (in weeks), start times, end times, total float (the amount of extra time available to complete an activity), free float (the amount of extra time available between two activities) and predecessors (activities that must be completed prior).

To calculate the duration of a project using these resources, first use the network diagram to map out all the referenced activities with arrows pointing from predecessor activities to successor ones. Using this graph, it should now be possible to draw lines tracing through each activity until reaching an endpoint; these lines represent potential paths through which work can progress towards completion. To find out which one is considered “critical” or most important; compare all paths against each other in order determine longest one possible . This will provide insight into when deadline need met by due since any task lying along such route must done order reach finish line without running over any allotted allocated time frames.
