"Quick Reading of IDEF3 Process Descriptions: An Example.
An example approach for reading a schematic is described in the following steps. This outline for reading a schematic would be repeated, with few modifications, for all decompositions, whether found in a Process Schematic or an Object Schematic. In general, decompositions are read after the parent schematic has been read and understood.
The Big Picture.
A crucial step in the description-reading process is to understand the big picture
relevant to the real-life situation described. This big picture can be gained by reading and understanding the statement of purpose, statement of scope, objective of the scenario being described, and viewpoint of the IDEF3 Process Description. ...
Scan the Schematic.
Readers should become familiar with the scenario by scanning the schematic from left to right. This involves becoming familiar with the individual elements (e.g., UOBs, links, and junctions) displayed in the schematic. This is not an in-depth study of the schematic; rather, it provides readers with a general impression of the process being described and an overall understanding of the logic flow in the scenario.
Understand the Description.
In this step, readers gain a detailed understanding of the schematic associated with a scenario, object, or a decomposition of a schematic element. This is the part of the communication process that is most individualized and requires the most time. It is helpful to partition the schematic into understandable pieces."

"The schematic in Figure 2-2 represents an Object Schematic for the Order Material scenario derived from the business owner’s description. This example happens to illustrate a Transition Schematic since it characterizes the nature and structure of object state transitions for occurrences of the Order Material scenario. A key document in this process is the Purchase Request form. This form is eventually transformed into a Purchase Order (PO) via the Order Material process. A circle containing the name of an object represents an object of a certain kind (e.g., Purchase Request, Account Manager, Project). These labeled circles are known as kind symbols. A certain kind of object being in a certain state is represented by a circle with a label that captures both the kind itself and a corresponding state, thereby representing the type (or class) of objects that are in that state (within a given process). ... One of the first steps to develop an Object Schematic is to identify the possible states in which the object can exist. Though a real-world object often evolves through a continuum of states, an Object Schematic focuses on those distinguished states of particular interest to the domain expert. The transition arcs (arrows with triangular, filled-in heads) connecting the circles symbolize a state transition, the activity of changing from one state to another. The conditions that establish when an object is in a given state, how it exists a state, how it can transition between states, and how it can enter a new state are recorded on a special form. The banded boxes linked to the arrows (called referents) are aids to describe the relationships between objects states and UOBs, scenarios, or other Transition Schematics that participate in a scenario occurrence. ... The transition junctions containing an “X” (for exclusive or) indicate the choice of exactly one path among several possible paths in an occurrence."
