Project Management

D Explanation: If resources are adequate but the demand varies widely over the life of the project, it may be desirable to even out resource demand by delaying noncritical activities (using slack) to lower peak demand and, thus, increase resource utilization.This process is called resource smoothing.

A Explanation: If resources are not adequate to meet peak demands, the late start of some activities must be delayed, and the duration of the project may be increased.This process is called resource-constrained scheduling.

E Explanation: The consequences of failing to schedule limited resources are a costly activity and project delays usually manifest themselves midway in the project when quick corrective action is difficult.
