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.

Answer 1

Answer:

The correct answer is letter "A": Crashing is not possible unless there are multiple critical paths.

Explanation:

Project crashing is a technique used to reduce the duration of a project to the least amount of extra cost by decreasing one or more critical activities. All of this is usually arranged in multiple entry charts where each critical activity receives the name of "critical path". It is imperative to have several critical paths so the crashing can be the most effective possible.
