Because of the positive results, the Department of Defense identified the need for standardization of the IETM development. In 1987 a joint military and commercial group was formed consisting of the Office of the Secretary of Defense Computer-assisted Acquisition and Logistics Support (OSD CALS) and Aerospace Industries Association (AIA). This group developed concepts for IETM authoring, IETM presentation and data interchange which were used as the basis for standard development. In 1989 the US Navy, Air Force and Army formed an ad-hoc group to determine the best way to create standards for IETMS. Input from the use of NTIPS and CMAS, later renamed Integrated Maintenance Information System(IMIS), were used along with input from the CALS Industry Steering Group (ISG) Paperless Technical Manual Committee, the Navy A-12 Program, The Air Force ATF Program, and the Army PMDE Program's IETM Style Guide as a starting point for a working group for IETM standards. The group came out with the first formally issued set of standards in 1992. By 1994, Senior R&D Engineer Michael Weldon, working on behalf of LORAL Corporation, developed a demonstration White Paper IETM describing the use of an IETM utilizing an eyeglass Monitor interfaced with a portable belt mounted CD Player for hands free use by technicians in the field, i.e. as when working on a tower 60 feet AGL.
