Schedule
compression
The critical path is the sequence of activities that
represents the longest path 
Critical chain method is a schedule method that allows
the project team to place buffers on any project schedule path to account for
the limited resources 
Resource Leveling
Start &
end dates of activities adjusted so that supply & demand of resources is
balanced.
Leveling
resources typically results in a longer critical path.
