The arrow diagramming method shows the required order of tasks in a project or process, the best schedule for the entire project, and potential scheduling and resource problems and their solutions. It is used for scheduling and to determine the critical path through nodes. Variation: PERT (program evaluation and review technique) chartĪn arrow diagram is defined as a process diagramming tool used to determine optimal sequence of events, and their interconnectivity. Quality Glossary Definition: Arrow diagramĪlso called: activity on arrow diagram, activity network diagram, network diagram, activity chart, node diagram, CPM (critical path method) chart
