Question 30

Which of these statements regarding project crashing is true?
Crashing is not possible unless there are multiple critical paths.
Activities not on the critical path cannot become critical after crashing.
Crashing shortens the project duration by assigning more resources to one or more of the critical tasks.
Crashing a project often reduces the time it takes for lengthy or complex, but noncritical activities.
