OK, let me see if I understand this. Suppose tasks A, B, C, and D all have
a Duration of 5 days. Are you saying that if task A now has a Duration of 8
days, then you want B, C, and D to have a new Duration of 8 days as well?
If so, this is not possible in Microsoft Project without you manually
changing the Duration of those three tasks. On the other hand, if you are
saying that if task A slips by 8 days, you want the Start and Finish dates
of B, C, and D to slip by 8 days as well, then this is very possible. You
simply need to link those tasks with a Finish To Start (FS) dependency. To
do this, select the tasks that must occur in order and then click the Link
Tasks button on the Standard toolbar. Let us know if this helps.
