Which diagram displays the order of tasks in a project and potential scheduling problems?

The correct choice effectively represents both the sequence of tasks in a project and identifies potential scheduling problems. An Activity Network Diagram, also known as a project network diagram or a PERT (Program Evaluation and Review Technique) chart, visually maps out each task, its dependencies, and the overall workflow of the project. It showcases the relationships between tasks, helping project managers to see how delays or changes in one area can affect the overall timeline.

This diagram is particularly valuable in project management as it emphasizes the critical path, which is the longest sequence of dependent tasks that determines the shortest time to complete the project. By analyzing this path, project managers can anticipate scheduling issues and proactively address them, ensuring more efficient project execution.

In contrast, a Gantt Chart primarily displays tasks along a timeline but does not inherently show the dependence between tasks or identify potential scheduling problems as clearly as an Activity Network Diagram does. Flowcharts are used for illustrating and analyzing processes, while the Process Decision Program Chart focuses on decision points and outcomes rather than task sequencing in projects.
