In Critical Chain Project Management (CCPM), what is the recommended buffer sizing approach when dealing with multiple dependent tasks that have high uncertainty?
a.
Apply a standard 30% buffer to each task and add an extra 20% buffer at major milestone points
b.
Add 50% of the combined task duration estimates as a project buffer after identifying and sequencing the critical chain
c.
Calculate the sum of all task uncertainties and distribute the buffer proportionally across all dependent tasks
d.
Add individual buffers to each task based on their respective complexity levels and then combine them at project completion
