We're working on a project that has a considerable amount of task insertion risk (by which I mean either a) the insertion of new tasks into the WBS or b) the rearrangement of technical dependencies in the project network). Despite our best efforts on the WBS phase, we still find ourselves constantly revising the WBS/project network as we learn more about the domain.
My experience is with scheduling tools (e.g. PERT, Monte Carlo) that focus on task duration risk. I'm finding myself very poorly equipped to deal with constant changes to the WBS/project network themselves.
Are there more appropriate tools for me to use for scheduling/control in the presence of high task insertion risk? If so, what are they? I've taken a look at Critical Chain / Buffer Management but am not sure if this is the answer.
