There are two types of process logic diagrams - process dependency diagrams (PDD) and logical data flow diagrams (LDFD). They serve similar purposes. To perform this task, select either diagram type, but do not attempt both as it would be largely a redundant exercise. The scope (context) of either type of diagram would be a theme (the set of processes which produce the response to a business event. Therefore, there would be created a series of either PDDs or LDFDs containing all elementary processes which are within the scope of the area of analysis.
Draw process dependency diagram (PDD)
Develop a set of process dependency diagrams that show, between them, all elementary processes.
¤ Start with a theme (event model) containing the processes which produce the response to a business event. This selected theme is the context for the PDD.
Draw one dependency diagram for each theme. Make sure that every elementary process within that theme is included in the diagram.
¤ Correlate the Decomposition Diagrams with the Dependency Diagrams
You will probably find errors in the decomposition diagrams while you are drawing the dependency diagrams. Correct the decomposition diagrams so that they remain consistent with the evolving dependency diagrams.
¤ Verify the Consistency of Dependency Diagrams
Verify the consistency of these dependency diagrams by ensuring that every elementary process is contained in at least one PDD.
There will result a dependency diagram for each business event previously identified by the user community.
¤ The dependency diagrams will be validated by the users who either perform or who are accountable for the performance of the processes represented in each diagram.

Build logical data flow diagram (LDFD)
¤ Develop a data flow diagram for each theme.
The scope or context of the data flow diagram is the set of elementary processes comprising a theme. The external agents reflect the business event which triggered the theme, the response to the business event and any other sources of information or recipients of information or resources of the processes included in the theme. Place the external agents on the same diagram as the elementary processes.
