Critical path or critical chain--combining the best of both

Critical Chain Project Management (CCPM) is frequently compared and contrasted with the more traditional Critical Path Method (CPM) approach. This article offers a hybrid approach called the Critical Brain Technique (CBT), and applies it to duration estimating, scheduling, and progress tracking. CCPM bases its schedule on a mean, whereas the PERT estimating approach uses the most likely value which allows, among other benefits, tighter scheduling. CPM uses float to represent an outcome of the task dependencies, whereas CCPM uses buffers to absorb variations from the original estimate; these methods can be combined to yield the bestfrom both. CPM and CCPM both provide different perspectives to some important issues, and there are advantages to be reaped by using both appropriately.
