"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."
