3. Precedence Diagramming Method (PDM)
The precedence diagramming method (PDM) is the
most common method of arranging the project work
visually.
The PDM puts the activities in boxes, called nodes, and
connects the boxes with arrows. The arrows represent
the relationship and the dependencies of the work
packages.

4. The illustration below shows a simple network
diagram using PDM:

5. PDM includes four types of dependencies or
precedence relationships:
Finish-to-Start (FS). This relationship means Task A
must complete before Task B can begin. This is the
most common relationship. For example, the
foundation must be set before the framing can begin.
The initiation of the successor activity depends upon
the completion of the predecessor activity.

6. Finish-to-Finish. This relationship means Task A
must complete before Task B does. Ideally, two tasks
must finish at exactly the same time, but this is not
always the case. The completion of the successor
activity depends upon the completion of the
predecessor activity.

7. Start-to-Start. This relationship means Task A must
start before Task B can start. This relationship allows
both activities to happen in tandem. The initiation of
the successor activity depends upon the initiation of
the predecessor activity.

8. Start-to-Finish. This relationship is unusual and is
rarely used. It requires that Task A start so that Task B
may finish. Such relationships may be encountered in
construction and manufacturing.
It is also known as just-in-time (JIT) scheduling. The
completion of the successor activity depends upon the
initiation of the predecessor activity.

9. In PDM, finish-to-start is the most commonly used
type of precedence relationship. Start-to-finish
relationships are rarely used.
This technique is also called Activity-On-Node (AON)
and is the method used by most project management
software packages. It includes four types of
dependencies or precedence relationships
