How is the critical path of a network diagram defined?

Start-D-E-Finish
Start-C-E-Finish
Start-D-E-F-Finish
Start-B-F-Finish

The correct answer is: Start-C-E-Finish

The critical path of a network diagram is defined as the longest sequence of tasks that must be completed for the project to finish on time. It identifies which tasks are critical in terms of time and have no slack; any delay in these tasks will directly impact the project's overall timeline. In the context given, the correct answer highlights a sequence of activities that constitutes the critical path. It reflects that the pathway starting with the initial task, moving through significant intermediary tasks, and concluding at the project finish point comprises the activities that dictate the project duration. To effectively identify the critical path, it generally involves calculating the duration of multiple sequences through the network diagram and determining which path has the longest total duration. In the example provided, the listed path shows an accurate sequence that keeps the project timeline intact. It’s important to note that the other choices may depict valid tasks; however, they represent paths shorter than the critical path or do not maintain the necessary sequencing that would affect the overall duration of the project, illustrating why they do not represent the critical path in this scenario.
