1. Digital Transformation of Defence Maintenance
The Indian Armed Forces are moving away from paper-based technical manuals toward digital, interactive, and network-enabled documentation.
This shift aligns with India’s push for:
Digital India mission
Indigenization under “Atmanirbhar Bharat”
Smart maintenance and logistics management systems
Hence, IETM (Interactive Electronic Technical Manual) has replaced bulky printed manuals as the new standard.
2. Standardization Through JSG 0852
Earlier, every vendor or OEM had their own format PDF, HTML, Word, etc. This created problems in integration, updates, and training.
To solve this, the Directorate General of Quality Assurance (DGQA) and the Directorate of Standardisation introduced JSG 0852:2019, an Indian Defence Standard that:
Defines a common structure, database format, and interaction model for IETMs.
Ensures uniformity across all documentation supplied to Indian Defence.
Mandates Level 4 (database-driven) IETMs for complex systems.
3. Operational Efficiency and Faster Fault Diagnosis
Defence systems like ships, aircraft, radars, vehicles are complex and maintenance intensive.
IETMs allow:
Instant access to fault isolation guides, step-by-step procedures, and interactive schematics.
Reduced Mean Time to Repair (MTTR) and improved operational readiness.
This real-time accessibility has made IETMs indispensable during missions and in field conditions.
4. Lifecycle Management and Easy Upgradation
Traditional printed manuals quickly become outdated after system upgrades or modifications.
IETMs make it possible to:
Easily update content and manage versions.
Maintain a single-source database for all changes throughout the equipment lifecycle.
Support configuration control demanded by DGQA and the Services.
