Accompanied by Segregation of Duties, Rotation is a useful security measure which has, in the past, uncovered a number of users nefarious activities. In days gone by rotation was particularly important for staff such as cashiers in the habit of fiddling their till balances. Now it is aimed more at staff who use organisation computer systems.

Alternatively it may serve merely to prove that all is in order. Either way it is useful to know.
