No reviews yet
Anyone researching Interactive Electronic Technical Manuals (IETMs) quickly runs into a recurring term: "levels." Documentation is described as Level 1, Level 2, all the way up to Level 4 or 5, but what actually changes between these levels, and why does it matter which one an organization chooses?
Level 1: Digitized, but static
Level 2: Cross-referenced navigation
Level 3: Structured, database-driven content
Level 4: Fully interactive
Level 5: Predictive and integrated
The level system is essentially a way of describing how interactive and structured a piece of technical documentation is. Historically, this classification (and in India, formalized under standards like JSG 0852) was used to define exactly what capabilities a defence contractor needed to deliver alongside their equipment. Newer approaches sometimes favor a "functionality matrix" instead of strict levels, specifying required features directly (search, multimedia, diagnostics, etc.), but the level terminology remains widely used and understood.
