IETM - Interactive Electronic Technical Manuals

Widespread delivery of data — centralized updates — easy edits

IETM Interactive Electronic Technical Manuals

Interactive Electronic Technical Manuals

IETM / IETP technology puts information where it's needed. Faster, better and more accessible. Interactive information - on-demand electronic manuals are the most efficient, cost-effective method to control, deliver and maintain data.

Properly authored IETMs allow operators and maintenance personnel to locate needed information far more rapidly than paper manuals. The information is often displayed locally to the problem (on-board systems, for example) and visual information intuitively presented typically supplies a speedier resolution.

From the authoring and updating side, complete IETM systems allow information authors to improve control of content and to distribute changes and updates quickly.

A paperless, interactive environment of contextual information can drive faster and more accurate responses throughout your process.

We can repurpose your existing legacy data, develop new elements and integrate everything into a flexible 'information on demand' system responsive to your environment's requirements.

DTB Technical Services Division can develop IETMs to any standards and requirements. Contact us with your project information to see how we can help.

DTB's extensive capabilities, combining complete technical publications with our engineering and testing facilites are represented on our main website. See more about IETM Development at

Elements of Interactive Information Systems

Technical Writing Services - Interactive data delivery starts with information and so do we. DTB can review your existing files and provide fresh insight into how they may be re-used, updated and converted. Dayton T. Brown routinely authors new information as well, studying and understanding your projects and requirements to provide a structured data system that grows with your needs.

STRUCTURED DATA DEVELOPMENT — Data authored to today's standards is adaptable, and can be used and reused at any point downstream. XML and SGML often provide the framework for the flexible utilization of information, connecting your resources to the most advantageous point of use. DTB's teams specialize in these and many other structured data formats, authoring to all required standards, such as S1000D, MIL standards and more.

Check the PTC User Community for informative threads about IETM development.

TECHNICAL ILLUSTRATION SERVICES — Our graphic and illustration services range from the conversion of legacy graphic file types to the development of 'intelligent graphics' that enhance the use and users' connectivity with the flow of information. We can start from scratch, creating new drawings of your parts and processes or re-purpose your existing computer graphic files for reuse in new systems.

Intelligently designed interactive information systems, including IETMs, can deliver information throughout the entire range of process at new speeds. Updates can be instantaneous across your entire system. Users can activate pinpoint delivery of precisely the information they require. Finally, your data, broadcast through a system responsive to your requirements, will be supporting your entire range of activity.

DTB Technical Services Division has provided a wide range of documentation products, analysis and support services to the military, government and commercial industries since 1966. We have a long record of evolution with changing technologies and often lead the way in the development and acceptance of emerging standards.

DTB can provide alternatives and insight into the new opportunities evolving technologies present. Contact DTB's Technical Services Division for a concise evaluation of your requirements.

Classes of IETMs

A functionality matrix is used as a checklist of which features are required for an checklist more precisely defines what functionality an IETM has, and allows clearer communication between an IETM developer and the IETM customer. Classes and levels of IETMS are no longer regarded as acceptable descriptors of IETMs.

The IETM functionality matrix was first developed by the US Aerospace Industries Association (AIA) Product Support Committee. It is used in most US military technical data specifications as well as S1000D, the international IETM standard.

Wikipedia has some generalized and interesting information about IETM history and use.

Class 0 Paper - Printed manuals. TYPE I
Class 1 Electronically Indexed Page Images - Page images rather than live text, intelligent graphics, etc. may contain rudimentary linking within document internal structure.
Class 2 Electronic Scrolling Documents - Live text with SGML/XML tags. May include multimedia. Internal linking.
Class 3 Linear Structured IETMs - Utilizes SGML or XML. Most often viewed as an indexed PDF file (page turner).
Class 4 Hierarchically Structured IETMs - Fully structured hierarchy of information specifically authored for the IETM. Dynamic cross-reference features. Typically a relational or object-oriented database stores data tagged with SGML / XML. Robust search features. TYPE II
Class 5 Integrated Process IETMs - Systems that go beyond providing information, but actually interact with hardware and process equipment. Provides strong:
• Diagnostics • Remote Diagnostics • Intrusive Diagnostics
• Expert Systems • Test Equipment • Prime Equipment Diagnostics
