1. Network diagramming is a logical, sequential process that requires you to consider the order in which activities should occur so projects can be scheduled as efficiently as possible. There are two primary methods for developing activity networks, PERT and CPM. PERT, which stands for Program Evalua- tion and Review Technique, was developed in the late 1950s through collaboration between the U.S. Navy, Booz-Allen Hamilton, and Lockheed Corporation for the creation of the Polaris missile program. PERT originally was used in research and development (R&D), a field in which activity duration esti- mates can be difficult to make, and resulted from probability analysis. CPM, or Critical Path Method, was developed independently at the same time as PERT by DuPont, Inc. CPM, used commonly in the construction industry, differs from PERT primarily in the assumptions it makes about estimating activ- ity durations.
