Where did you learn this standard of argument? Characterizing OPMS as nothing but empty list making is just that, a characterization. It is our summary of the worth of OPMS in a single sentence. It is no different than my characterization of all of the PERT charts of the 70's and 80's amounting to nothing but a waste of trees. Are you suggesting that that your critics be limited to describing OPMS only in your terms? What kind of universe would that be?
