18.Suppose you created your activity network and discovered that you had two critical paths in your project. You share this information with another project manager, who strongly argues that a project can have only one critical path; therefore, your calculations are incorrect. What is the correct response to his assertation?

A project can have more than one critical path, although having multiple critical paths

is also likely to increase the risk of the project falling behind.

Your coworker is correct: a project can have only one critical path. You need to return

to the network and determine where you erred in developing the network logic and

diagram.

The critical path is the shortest path through the network, so having more than one is

not a significant problem.

A project can have more than one critical path, although having multiple critical paths

is actually likely to decrease the overall risk of the project.
