Which of the following best describes resource levelling in project scheduling?
Resource levelling means shifting activity start dates, mainly using available float, to smooth the demand for resources and avoid peaks. It may lengthen the project if resources are constrained, unlike crashing, which shortens duration at extra cost.
- AShortening the project duration by adding resources to critical activities
- BAdjusting activity start dates to smooth resource demand, using float where possible, even if duration may extendCorrect
- CReducing the cost of each activity to its normal cost
- DCrashing all activities by an equal number of days
Explanation
Resource levelling reschedules activities, usually within available float, to avoid peaks and troughs in resource usage. If resources are limited, it may extend the project. Crashing, by contrast, shortens duration by spending more.
Did you get it right without looking?
One question tells you little. A timed set on Project Management, Monitoring and Control shows your real accuracy, how long you take and where you lose marks.
