Based on the results of the investigation carried out on the 115 firms
examined, there seem to be three different types of general use of a PMS,
obviously compatible with each other (Table IV):
(1) planning, control and coordination of the activities;
(2) control, evaluation and involvement of the human resources;
(3) benchmarking (that is the comparison with performances of the
competitors and/or best firms (Sweeney, 1994)).
