The Precedence Diagramming Method (PDM), a strategy for scheduling stages in a task plan, creates a project schedule network diagram that employs nodes to represent activities and connects them with shoots to represent dependencies. This precedence diagram is also known as the activity-on-node diagram (AON). Identifying and describing the grouping and dependencies of exercises in a project or a section of a project, such as a workstream or a working bundle, is part of the technique. The mo may represent four different types of dependencies, also known as intelligent connections, as described in the following Precedence diagram generator. The relationship between successor tasks and archetype tasks, which appear as nodes in the outline, is structured by these dependencies. This is similar to the activity-on-node or activity-on-arrow approach, but it is more advanced than the rest.
