An intelligent user interface sometimes needs to present a sequence of related recommendations to a user, in spite of being uncertain in advance as to whether (and with what success) the user will follow each recommendation. There are potential advantages to the use of decision-theoretic planning methods which yield an optimal policy for the situationdependent presentation of recommendations. This approach is discussed with reference to an example involving route instructions given by an airport assistance system.
