A project's duration can be reduced by: Shortening the duration of critical path tasks. Adding tasks to the critical path. Completing the backward pass first. Adding shorter routes around the critical path.

Shortening the duration of critical path tasks.

Explanation:

The critical path method is relevant for achieving effective project management. By visualizing the project's activities, it is possible to analyze the time needed to complete the tasks and avoid possible delays. The possibility of calculating the duration of completion time, the longest or the shortest, for each activity, also helps in reducing uncertainties, as it helps in reducing the unexpected surprises that may occur in the project.

This method also guarantees the advantage of helping to reduce project time by the possibility of visualizing which tasks can be reduced, as the method generates a greater understanding of the project's deadline as a whole, allowing a clearer view on which tasks can be changed and which should remain unchanged.
