Resetting critical path

[Jpstewar]

I note that there's a setting in Project that says, "Tasks are critical if
slack is less than or equal to 0" by default. Why would you ever want to
change this?

You might work for an organisation where senior management want
forewarning of tasks that may become critical before they do so for
example so that they can take pre-emptive action.
