From Classes to Capabilities: The Evolving Landscape of IETMs
Introduction:
In 1994, Eric L. Jorgensen’s groundbreaking classification system revolutionized Electronic Technical Manuals (ETMs). This system, adopted by the military, laid a solid foundation for ETMs across the services. However, as technology advanced, so did the requirements for ETMs. In 2003, the Functionality Matrix emerged, offering a more flexible and adaptable approach.
The Shift from Classes to Capabilities:
The original classification system, with its six distinct classes, provided a framework for understanding ETM capabilities. However, the Functionality Matrix, introduced with S1000D v2, offered a more granular and dynamic approach. This matrix enabled Interactive Electronic Technical Manuals (IETMs) to provide all the capabilities of the original classes while also incorporating new functionalities that were previously unimaginable.
The Enduring Legacy of Class Terminology:
Despite the shift to the Functionality Matrix, the term “Class 6” has persisted in military circles. This term, which never existed in the original classification system, has been used to describe advanced IETMs that offer a level of interactivity and efficiency far beyond what was possible with earlier ETMs.
A Case Study: The “Class 6” IETM
One notable example of an advanced IETM is the “Class 6” IETM developed by ONEIL for the U.S. Army in 2005. This IETM, which incorporated Built-In Test (BIT) sensors and a sophisticated diagnostic system, offered a level of interactivity and efficiency that was unprecedented at the time.
Key features of this IETM included:
- Autonomous Diagnostic Manager: Automated diagnostic testing across multiple subsystems.
- Distributed State Table: Storage of sensor data or “evidence.”
- Intrusive Diagnostic Module: A logic tree for assessing conditions.
This IETM, which is still in use today, demonstrates the enduring value of advanced IETMs and the importance of staying current with technological advancements.
Conclusion:
While the original classification system has evolved, its legacy remains evident in the terminology and foundational concepts of IETMs. The Functionality Matrix offers a more flexible and adaptable approach, enabling IETMs to meet the ever-changing needs of the military. The “Class 6” IETM serves as a testament to the power of advanced IETMs and the importance of continuous innovation in military documentation.
