"As with the Process Schematic, the correctness of the Object Schematic and
associated elaborations are confirmed through validation with the domain expert. After reviewing the Transition Schematic, the domain expert observes that the allowable state transitions displayed in the schematic do not include those representative of a failed request. ...
The domain expert also identified transitions through which the identity of the object was preserved and transitions where the object was actually transformed into an entirely different object. The domain expert’s comments to the analyst yield the schematic
depicted in Figure 5-21." [IDEF3 Process Description Capture Method Report AL-TR-1995-XXXX. idef.com/ pdf/ Idef3_ fn.pdf]

"Process schematics tend to be the most familiar and broadly used component of the IDEF3 method. These schematics provide a visualization mechanism for process-centered descriptions of a scenario. The graphical elements that comprise process schematics include Unit of Behavior (UOB) boxes, precedence links, junctions, referents, and notes. Referents and notes are constructs that are common across process and object schematics. Each of the graphical elements used for developing process schematics is presented below, together with discussions of how to formulate more complex statements using those graphical elements. The discussion begins with the most fundamental of these building blocks: the UOB." [IDEF3 Process Description Capture Method Report AL-TR-1995-XXXX. idef.com/ pdf/ Idef3_ fn.pdf]

"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."

"An IDEF3 schematic, whether a Process Schematic or an Object Schematic, is usually read starting with the leftmost element in the schematic. Conventionally, a schematic is read from left to right. To obtain an overview of the described scenario, a mental walkthrough of the schematic is performed. During a mental walkthrough of a Process Schematic, for example, the reader notes precedence relationships and the logical layout of the UOBs. Such a reading will provide a general understanding of the system." [IDEF3 Process Description Capture Method Report AL-TR-1995-XXXX. idef.com/ pdf/ Idef3_ fn.pdf]

"Additional context-setting information is then added to the Transition Schematic as required. For example, the domain expert’s description indicated that purchase requests involving direct projects require an authorization signature. Additionally, the description included discussion of a constraint that account managers or their designated backups must approve all requests involving their projects. This information is noted directly on the schematic. The resulting Object Schematic is displayed in Figure 5-22."

"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."
