Using the critical path method to schedule projects began in the late 1950s, with two simultaneous, unrelated projects. This approach, referred to as the activity-on-node (AON) or precedence method, caught on rapidly and has supplanted the earlier activity-on-arrow (AOA) method in nearly all uses.” How the Critical Path Method Was Created Fondahl, a professor of construction management at Stanford University, proposed in a 1961 paper that each task be represented by a node – square, circle, or oval – and the nodes be tied together with lines or arrows representing the sequence between tasks. This approach persisted for a decade, when a different method, with the same results, became popular. Professor John W. “The original critical path method used arrows to represent tasks and tied them together by connecting their beginning and end at nodes, so that proper sequencing was developed. In fact, the original critical path method was done by hand. Bennett points out that critical path has come a long way.
In addition to his books, he has written more than 50 professional papers and articles on topics ranging from construction management to network techniques for project scheduling.ĭr. He has also spent 29 years on the engineering faculty at the University of Alaska Fairbanks, teaching undergraduate and graduate courses in technical management, including project management and scheduling. He has applied critical path scheduling to a wide variety of projects since 1965.
