According to the PMBOK the Critical Chain Method is a schedule network analysis technique that modifies the project schedule to account for limited resources. It mixes deterministic and probabilistic approaches to schedule network analysis.
Some of its advantages are:
Planning and control processes.
Remove bottleneck to resolve constraints.
Eliminate waste.
Reduce Variations.
On the cons side, the construction of a latest start schedule has one major disadvantage which might endanger the project deadline. Since all activities are scheduled as-late-as-possible, none of the activities have a positive slack value and hence all activities are critical.
