What is a major advantage of using CPA in project management?

Using a Critical Path Analysis (CPA) provides a significant advantage in project management by facilitating the visualization of every step or task within a project. This method allows project managers to identify which activities directly impact project completion time, thus making it easier to map out the sequence of tasks, understand their relationships, and assess the overall project timeline.

By visualizing the project's critical path, project managers can prioritize essential tasks, monitor progress, and allocate resources effectively. This clear overview not only aids in planning but also in identifying potential delays and areas requiring extra attention, leading to more informed decision-making throughout the project lifecycle.

The other options suggest benefits that CPA does not inherently provide. For instance, while CPA can help optimize scheduling and resource usage, it does not guarantee the completion of all tasks nor does it eliminate task dependencies, as dependencies are crucial for understanding how tasks relate to each other. Additionally, while CPA aids in resource allocation, it does not necessarily ensure maximum resource allocation but rather focuses on managing the timeline and sequence of project activities effectively.
