Document Summary
Activities project steps that consume resources and/or time. Activity on-arrow (aoa) network diagram convention in which arrows designate activities. Activity-on-node (aon) network diagram convention in which nodes designate activities. Beta distribution used to describe the inherent variability in activity time estimates. Cpm critical path method, for planning and coordinating large projects. Critical path the longest path; determines expected project duration. Events the starting and finishing of activities, designated by nodes in the aoa convention. Independence assumption that path duration times are independent of each other; requiring that activity times be independent, and that each activity is on only one path. Most likely time the most probable length of time that will be required. Network (precedence) diagram diagram of project activities that shows sequential relationships by use of arrows and nodes. Optimistic time the length of time required under optimal conditions. Path a sequence of activities that leads from the starting node to the finishing node.
