Resource-leveling can take the "work demand" and balance it against the resource pool availability for the given week. The goal is to create this weekly schedule in advance of performing the work. Without resource-leveling the organization (planner, scheduler, supervisor) is most likely performing subjective selection.
In a project plan, the critical chain is the sequence of both precedence- and resource-dependent tasks that prevents a project from being completed in a shorter time, given finite resources. If resources are always available in unlimited quantities, then a project's critical chain is identical to its critical path method .
In other words, in an Open Workbench plan, task schedule is driven by the number of hours each resource will work per week to cover the total number of hours required for the tasks, whereas Microsoft Project does the reverse by generating estimates for the resources based on the task duration rather than their work availability.
A resource-leveled schedule may include delays due to resource bottlenecks (i.e., unavailability of a resource at the required time), and may cause a previously shorter path to become the longest or most "resource critical" path while a resource-smoothed schedule avoids impacting the critical path by using only free and total float.

The goal of schedule compression is to shorten the project without amending the project scope, according to the schedule constraints, required time and other objectives.. Any compression must be done in the critical path activiti

The dependencies between the tasks can affect the length of the overall project (dependency constrained), as can the availability of resources (resource constrained). Time is different from all other resources and cost categories. Using actual cost of previous, similar projects as the basis for estimating the cost of current project.
