I hope that most academic programs are continually evaluating themselves and updating their classes.
But my question is broader. How often should a major, comprehensive review be made? What things should be considered? What suggestions do you have about process?
I realize that there may be some differences in academic disciplined, based on how much the field is changing. As you reply, please tell us YOUR discipline.
(Also, if you like the question, please up-vote the question as well as individual answers you like.)
