IETM Development

Contact DTB concerning the development of an interactive information system for your enterprise.

DTB creates IETMs for all requirements, military or commercial.

IETM Interactive Electronic Technical Manuals

DTB Technical Services Division can develop interactive electronic technical manuals to any standards and requirements. Contact DTB with your project information to see how we can help.

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 IETM 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.

DTB provides complete IETM authoring capabilities —

We research, write, illustrate and publish.

IETM – Control Your Information

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.
DTB can re-purpose your existing legacy data, develop new elements and integrate everything into a flexible information-on-demand system responsive to your environment’s requirements.

About Classes of IETMs
ietm classesClasses 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.

See Classes of IETM

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. (TYPE I)

Class 3 Linear Structured IETMs – Utilizes SGML or XML. Most often viewed as an indexed PDF file (page turner). (TYPE I)

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. (TYPE II) Provides strong

  • Diagnostics (Remote & Intrusive)
  • Expert Systems
  • Test Equipment
  • Prime Equipment Diagnostics


100's and 100's of IETMs — Years and Years of Experience



Tell us about your project

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.

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.

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.
