However, the object-oriented analysis method (OOA) is being given attention in information systems development. An experiment was conducted to compare the two methods in terms of effectiveness in systems analysis. The DFD method seemed to be easier to learn than the OOA method for inexperienced participants. However, after a certain period of training, participants who used the OOA method for systems analysis made fewer errors than those who used the DFD method. On the basis of this study, it is recommended that OOA be taught in business schools.
