Precedence Diagram Method (PDM) is a visual representation technique that depicts the activities involved in a project. It is a method of constructing a project schedule network diagram that uses boxes/nodes to represent activities and connects them with arrows that show the dependencies. The Program Evaluation and Review Technique (PERT) and Critical Path Method (CPM) techniques are essentially limited to “finish-start” relationships (i.e., activity B cannot start until activity A is completed). PDM was developed subsequent to the PERT/CPM techniques and its
function is to permit a more accurate depiction of relationships among various activities. How is the Precedence Diagram Method (PDM) DepictedThe Precedence Diagram is depicted by a chart with nodes and their relationships. An arrow connects two nodes to represent an active relationship. It’s also called a nodal diagram or network diagram. Precedence Diagram Method (PDM)Precedence Diagram Method (PDM) BenefitsThere are a lot of benefits that can be obtained by using the PDM. These are:
The Four Precedence Diagram Methods (PDM)The PDM has four ways of developing the diagram. These methods are:

How a Precedence Diagram Method (PDM) Helps Program ManagersNetwork scheduling techniques provide Program Managers with a powerful tool for scheduling and controlling their programs/projects. In general, they permit the graphic portrayal of project activities and relationships among the activities. This provides the basis for determining the project’s critical path, predicting shortages, and identifying possible reallocation of resources to solve problems. Through the use of readily available software, network schedules are fairly easy to update and rework, thus providing managers with current program/project status information and control over activities and schedules.

Updated: 9/7/2022 Rank: G1.5 What is network diagram of PERT and CPM?PERT applies an “Activity-on-Arrow” network diagram, whereas CPM applies an “Activity-on-Node” network diagram. Activity-on-Arrow means the network diagram depicts each milestone event as a node, and shows the activity information on the arrows joining each milestone event.
What is a network diagram which is used by the PERT and CPM project management techniques multiple choice question?A PERT chart is a network diagram used in the Program Evaluation Review Technique (PERT) to represent a project's timeline. It allows project managers to estimate the duration of projects based on the analysis of task sequences.
