"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."

"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."

"Object Schematics.
IDEF offers a series of building blocks to express detailed object-centered process information; that is, information about how objects of various kinds are transformed into other kinds of things through a process, or how objects of a given kind change states through a process.
- Objects : An object of a certain kind, like a chassis, will be represented simply by a circle containing an appropriate label.
- Object States : A certain kind of object being in a certain state will be represented by a circle with a label that captures the kind itself and a corresponding state, representing thereby the type, or class, of objects that are in that state.
- Object schematics : The construction of complex representations built from kind symbols and object state symbols.
- Transition Schematics : The first and most basic construct is the basic state transition schematic or simply, transition schematic." [IDEF3. Wikipedia]

"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 processcentered descriptions of a scenario. The graphical elements that comprise process schematics include Unit of Behavior (UOB) boxes, precedence links, junctions, referents, and notes. The building blocks here are:
- Unit of Behavior (UOB) boxes.
- Links: Links are the glue that connect UOB boxes to form representations of dynamic processes.
- Simple Precedence Links: Precedence links express temporal precedence relations between instances of one UOB and those of another.
- Activation Plots: Activation plots are used to represent activations.
- Dashed Links: Dashed links carry no predefined semantics.
- Link Numbers: All links have an elaboration and unique link numbers.
Activation Semantics for Nonbranching Process Schematics.
- Junctions: Junctions in IDEF3 provide a mechanism to specify the logic of process branching.
- UOB Decompositions: Elaborations capture and structure detailed knowledge about processes.
- UOB Reference Numbering Scheme: A UOB box number is assigned to each UOB box in an IDEF3 Process Description.
- Partial Descriptions: UOB boxes are joined together by links. Because of the description capture focus of IDEF3, it is possible to conceive of UOBs without links to other parts of an IDEF3 schematic.
- Referents: Referents enhance understanding, provide additional meaning, and simplify the construction (i.e., minimize clutter) of both process schematics and object schematics." [IDEF3. Wikipedia]
