The Code of Estimating Practice, seventh edition, published by the Chartered Institute of Building (CIOB) in 2009 suggests that the term ‘precedence diagram method’, or PDM, refers to:

A method of constructing a logic network using nodes to represent the activities and connecting them by lines that show dependencies.

The Precedence Diagramming Method (PDM) is a visual representation technique which is used to prepare the project schedule network diagrams and determine the critical path.
