The use case:
The business would like a task to be able to be marked as "In Progress" even if the predecessors are not fully completed, but don't want the task to be able to be completed before the predecessors are complete.
It looks like either Finish-Finish (ff) or Scheduled-Start (sd) should work, but I am still unable to prevent the task from not completing. It's more than likely I am misunderstanding the rules, but I have tried every single predecessor type and cannot prevent the task from completing before its predecessor is complete.
In the case below: I'd like either task 2 or 3 to be able to be moved into In progress, but not able to be completed until Task 1 is marked as complete. What should go in the predecessor columns?
Thanks in advance,
