During the project initiation phase, a PM needs to construct a project schedule and show the project dependencies. Which of the following should the PM use for this task?

The Waterfall method is a project management methodology, not a specific tool or technique for diagramming dependencies within a schedule.

The simulation method, like Monte Carlo analysis, is used for risk analysis and calculating probabilistic schedule outcomes, not for initially constructing dependencies.

The Precedence Diagramming Method (PDM) is a technique used for building a project schedule network diagram. It visually represents activity sequences and their logical relationships (dependencies) using nodes (activities) and arrows (dependencies), which is essential for constructing a comprehensive project schedule during the initiation phase.

The Critical Path Method (CPM) is used to calculate the longest path of planned activities and determine the earliest/latest an activity can finish, but it relies on an underlying network diagram (like PDM) where dependencies are already defined.
