PGMP · Question #123

You are the program manager for your organization and are working with Tracy, one of the project managers in your program. Tracy is having some trouble understanding the concept of the critical path…

The correct answer is B. It is the path that reveals the earliest date the project can finish. This question asks for the correct definition of the critical path in a project network diagram. The critical path is the longest path through the network, determining the earliest possible project completion date.

Question

You are the program manager for your organization and are working with Tracy, one of the project managers in your program. Tracy is having some trouble understanding the concept of the critical path in her project's network diagram. Which one of the following is the best definition of the critical path?

Options

  • AIt is the path that carries the most risk of project failure.
  • BIt is the path that reveals the earliest date the project can finish.
  • CIt is the path with the most important activities in the project.
  • DIt is the duration of all the project activities if the labor is summed.

Why each option

This question asks for the correct definition of the critical path in a project network diagram. The critical path is the longest path through the network, determining the earliest possible project completion date.

AIt is the path that carries the most risk of project failure.

The critical path is not defined by risk level; a path with high risk may have float and not be on the critical path at all.

BIt is the path that reveals the earliest date the project can finish.Correct

The critical path is the longest sequence of dependent activities in the project network diagram and has zero total float. Because it is the longest path, it determines the minimum time required to complete the project - meaning it reveals the earliest date the project can finish. Any delay on the critical path directly delays the project end date.

CIt is the path with the most important activities in the project.

The critical path is determined by duration and dependencies, not by the subjective importance of the activities contained within it.

DIt is the duration of all the project activities if the labor is summed.

Summing all project activity durations regardless of dependencies would overstate the project duration; the critical path accounts for parallel paths and sequencing.
