The precedence diagramming method (which is also known by the three letter anagram PDF) refers to a specific project management technique in which the project management team and or the project management team leader employs a schedule network diagramming technique in order to graphically represent any known and preexisting schedule activities via the use of boxes (which can also be referred to as nodes). Once all of these particular schedule activities have been graphically displayed in this box, or node format, at that point all of the individual boxes are linked together via the use of a line which represents any logical relationship (of if there are more than one, logical relationships) that are found to exist. The fundamental and most significant benefit to using the precedence diagramming method format technique is that it quickly and easily allows the project management team and or the project management team leader to view all schedule activities and their relationships with one another.
