Dependency Mapping

Dependency Mapping (DM) is a critical tool in project management, particularly for PMP certification aspirants, as it helps in understanding how different project tasks are interrelated. This process involves mapping out the dependencies between tasks, which can be of four types: finish-to-start (FS), start-to-start (SS), finish-to-finish (FF), and start-to-finish (SF). By identifying these dependencies, project managers can better predict and manage the sequence of activities, ensuring that resources and timelines are efficiently allocated and that project milestones are met on time.

For example, in a software development project, certain coding tasks may need to be completed before testing can commence, creating a finish-to-start (FS) dependency. Understanding and mapping these dependencies using tools like a Precedence Diagramming Method (PDM) or Network Diagramming can help project managers anticipate potential delays and resource bottlenecks, thus improving project planning and execution. In the context of the PMP exam, candidates will be expected to demonstrate their ability to apply dependency mapping to real-world project scenarios, showing a deep understanding of how project activities are linked and how changes in one activity can impact others.
