I have a Task records with Planned Start and Planned Finish. There is also a formula text field called Progress that updates based on a number of conditions. Is it possible to create a formula for Progress that changes to a warning if a Planned Start won't work due to a Predecessor, ie the Planned Start is set before the Planned Finish of the preceding task?

To my knowledge; the native predecessor fields will not calculate that.  You would need some a child table of dependancies to the tasks themselves.  Then a mess of formulas and conditionals passing to make it all happen.  We've done it a few times, but its not as straight forward as you'd hope.
