According to the PMBOK® Guide, specifically within the Sequence Activities process, the Precedence Diagramming Method (PDM) defines four types of logical relationships (dependencies) between activities.
Finish-to-start (FS): This is the most commonly used logical relationship. In this setup, a successor activity cannot start until a predecessor activity has finished.
Application to the Scenario: In construction, you logically cannot begin the " pouring of concrete " (Successor) until the " delivery of concrete materials " (Predecessor) has been completed. The first activity must Finish before the second can Start.
Analysis of Other Options:
A. Start-to-start (SS): A relationship where a successor activity cannot start until a predecessor activity has started. (e.g., leveling concrete can start as soon as pouring starts).
B. Start-to-finish (SF): A rare relationship where a successor activity cannot finish until a predecessor activity has started.
C. Finish-to-finish (FF): A relationship where a successor activity cannot finish until a predecessor activity has finished.
