3 Modeling Standards and Notation

This chapter includes examples of a model for each level as well as a list of the symbols and annotation used on each level.

This chapter includes the following sections:

• Section 3.1, "Level 0"

• Section 3.2, "Level 1"

• Section 3.3, "Level 2"

• Section 3.4, "Level 3"

• Section 3.5, "Level 4"

• Section 3.6, "Functional Allocation Diagram"

3.1 Level 0

Figure 3-1 is an example process model for level 0.

Figure 3-1 Sample Model: Level 0

Figure 3-2 shows the symbols and annotation used on level 0.

Figure 3-2 Allowable Symbols: Level 0

3.2 Level 1

Figure 3-3 is an example process model for level 1.

Figure 3-3 Sample Model: Level 1

Figure 3-4 shows the symbols and annotation used on level 1.

Figure 3-4 Allowable Symbols: Level 1

3.3 Level 2

Figure 3-5 is an example process model for level 2.

Figure 3-5 Sample Model: Level 2

Figure 3-6 shows the symbols and annotation used on level 2.

Figure 3-6 Allowable Symbols: Level 2

3.4 Level 3

Figure 3-7 and Figure 3-8 show an example process model for level 3.

Figure 3-7 Sample Model (1 of 2): Level 3

Figure 3-8 Sample Model (2 of 2): Level 3

Figure 3-9 shows the symbols and annotation used on level 3.

3.5 Level 4

Level 4 is not a model level. It is the tasks that appear on the models at level 3; level 4 is the leaves at the bottom of the branch of the tree.

3.6 Functional Allocation Diagram

Like level 4, the Functional Allocation Diagram (FAD) is not a model level. The FAD diagram is use to depict the Enterprise Business Services and operations that are used by the Application Integration Architecture for a particular integration. Figure 3-10 is a sample FAD diagram.

Figure 3-10 Sample FAD Diagram

Figure 3-11 shows the allowable symbols.

Functional and Composite Business Process Views

Our reference process models depict functionally scoped business processes.

Figure 3-12 depicts a functional business process view drilldown for all four levels (Order Fulfillment) as well as the FAD.

Figure 3-12 Functional Business Process View Drill-down, All Four Levels (Order Fulfillment) and the FAD

Our composite business flows depict end-to-end processes that span portions of several functional business processes (Order to Cash, Procure to Pay, and Design to Release, for example).

Figure 3-13 depicts the composite business process view drill-down at level 0 (Order to Cash).

Figure 3-13 Composite Business Process View Drill-Down, Level 0 (Order to Cash)

Figure 3-14 depicts the composite business process view drill-down at level 1 (Order to Cash).
