Final answer:
The least accurate statement regarding the Precedence Diagramming Method (PDM) is that it only displays finish-to-start relationships, as PDM can show multiple types of dependencies. PDM is synonymous with Activity on Node (AON) and is used for creating schedule network diagrams.
Step-by-step explanation:
The Precedence Diagramming Method (PDM) is a technique used in project management for constructing a schedule network diagram that represents project activities and their dependencies. The statement that is least accurate regarding the PDM is that it only displays finish-to-start relationships. This is false because, in addition to finish-to-start, PDM can show three other types of dependencies: start-to-start, finish-to-finish, and start-to-finish. So, the correct answer is:
3) The PDM only displays finish-to-start relationships
PDM, also referred to as Activity on Node (AON), does indeed represent the same thing as stated in option 1, and it is the output of sequencing activities, which makes option 2 accurate. Lastly, PDM is a type of schedule network diagram, making option 4 accurate as well.
