concept for the agilists.
From Critical Chain we learn that to protect the critical path and avoid 'merge bias' that destroys schedules, including agile schedules, we buffer to make parallel paths look tandem (serial, finish-to-start). CP uber alles was his mantra. And, Goldratt recognized the cumulative error of putting reserves at the task manager level; his idea: the PM should control reserves, buffering the whole project.
We should all take a moment and remember Eliyahu Goldratt.
