looping interfacing dangling splicing
path which takes into account the completion of the parallel activities ideal path by proceeding along which the project can be completed as per schedule shortest path for the earliest completion of the project longest path of the network from the initial to final event
CPM is activity oriented and adopts probabilistic approach PERT is activity oriented and adopts deterministic approach PERT is event oriented and adopts probabilistic approach CPM is event oriented and adopts probabilistic approach

minor projects medium projects major projects all the above
the start and/or finish of an activity or the group of activities the useful criterion a dummy activity a definite time interval

progress versus time resources versus progress activity versus resources time versus activity
it is difficult to judge whether an activity is completed or not sequence of activities is not clearly defined it is not possible to judge whether the activity is ahead or behind schedule all the activities represented are independent of each other
