The MPM method makes it possible to evaluate the duration of the realization of a complex project and to detect the parts of this project not supporting any delay. The information about the tasks is summarized in a schedule.
Unlike the PERT method, the vertices in the MPM method are to-do items. We can “consider” that the edges of the PERT method become vertices with the MPM method (in the same way for the vertices become edges).
Which gives the following graph:
