If resources are adequate but 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.
a rule of thumb used to make decisions. Frequently found in scheduling projects. For example, scheduling critical activities first, then schedule activities with the shortest duration.

Inefficient resource utilization
the following lists three of the more common problems encountered in managing multiproject resource schedules.
is one that must be completed by an imposed date. If required, resources can be added to ensure the project is completed by a specific date. Although time is the critical factor, resource usage should be no more than is necessary and sufficient.
techniques delay noncritical activities by using positive slack to reduce peak demand and fill in the valleys for the resources.
The peak of demand for the resource is reduced
Resources over the life of the project have been reduced
The fluctuations in resource demand were minimized.
