The finish-to-start relationship type is the most common in a project network diagram. It means that the predecessor activity must finish before its successor activity can start. For example, the carpet must be installed before the painting activity can begin. What is precedence diagramming method (PDM) in sequence activities? Precedence diagramming method (PDM) is used in critical path methodology for building a project schedule network diagram that uses boxes or rectangles, referred to as nodes, to represent activities, and join each other with arrows that show the logical relationship that exists between them. This technique is also known as Activity-On-Node (AON).It includes four types of dependencies or logical relationships: Finish-to-start(FS): The initiation of the successor activity depends upon the completion of the predecessor activity. Finish-to-finish(FF): The completion of the successor activity depends upon the completion of the predecessor activity. Start-to-start(SS): The initiation of the successor activity depends upon the initiation of the predecessor activity. Start-to-finish(SF): The completion of the successor activity depends upon the initiation of the predecessor activity.
