Precedence Diagramming Method (PDM):
* PDM allows for Start-to-Start (SS), Finish-to-Start (FS), Start-to-Finish (SF), and Finish-to-Finish (FF) relationships between activities.
* This flexibility makes PDM distinct from Arrow Diagramming Method (ADM), which uses arrows to depict dependencies.
Evaluation of Options:
* Option A: Incorrect. This describes ADM, not PDM.
* Option B: Incorrect. Both PDM and ADM can represent multiple critical paths.
* Option C: Incorrect. Late start and finish calculations apply to both methods.
* Option D: Correct. PDM uniquely allows multiple relationship types.
