Basic PTM - Calendar & Critical Path

For the Critical Path/Calendar assignments, you say assume (2) people, but we may have a third if necessary. Lets say we had budgeted for (4) on the Elements sheet. Should we alter the Elements sheet to reflect a maximum of (3) people, or just make that change on the Critical Path/Calendar and have the documents be out of sync? Basically, if we need to make a change, should we track changes backwards or not.

You can, should you so choose to rejigger your original estimate to reflect no more than the 2(sometimes+1) people available for the calendar assignment in order to force consistent lin times. If you do so, you do not have to update the earlier assignment.

Or you can do nothing and have the assignments not match, they are being evaluated individually.
