Defence documentation
Meeting the sector's operational and regulatory requirements

In the defence sector, defence documentation is a structural component of programmes, as essential as the equipment itself.
It governs systems operation, military maintenance, operational safety, regulatory compliance and knowledge transfer over long life cycles.
LCSI works alongside defence sector stakeholders to produce standardised documentation that is fully actionable in operational conditions.
The defence sector: a unique documentary environment
Defence does not operate with general documentation standards.
It imposes:
01
Strict normative requirements
02
A very precise documentation structuring
03
Consistency across deliverables
04
Full information traceability
05
Documentation usable in sensitve contexts
In this sector, a poorly structured or ambiguous document becomes an operational risk.
Standardised and binding documentary frameworks
Defence documentation must strictly adhere to clearly defined, often contractual, frameworks.
LCSI operates on projects governed by:
-
S1000D (International specification for technical publications)
-
MAT10000 and specific military references
-
Defence industry frameworks.
These frameworks dictate the content structure, the required level of detail, the terminology used, and the information delivery logic.

Technical illustration: a core expertise of LCSI
Beyond text, mastering visuals is at the heart of our work. For the defence sector, LCSI creates and updates high-precision technical illustrations.
Our services include:
Processing CAD data (digital models) to generate mechanical exploded views and 3D views.
Roducing plates for Illustrated Parts Catalogues (CATI) with integrated hotspots (interactive links for immediate part identification).
Creating maintenance diagrams and visual operating instructions to facilitate field interventions.
This ability to translate technical complexity into clear visuals ensures error-free equipment operation.

Complex systems and critical information
Defence equipment is often multi-technological, highly integrated, mission-critical, and subject to high security constraints.
Defence documentation must allow for rapid system understanding, interpretation-free operation, reliable maintenance and operational continuity.

Types of documents produced for the defence sector
Within the framework of defence programmes, LCSI produces a comprehensive range of standardised deliverables tailored for field use:
DTU - User Technical Documentation
TG - Technical Guides
MM - Military Maintenance Manuals
(Preventive and Corrective)
Operating Instructions and functional descriptions
CATI - Illustrated Parts Catalogues (including hotspot management and interactivity)
Technical supports associated with field operations and maintenance.
Each deliverable is designed to fit into a consistent documentation suite, ensuring a seamless flow of information without gaps.

An approach oriented towards real-world use and compliance
Defence documentation must be understandable by end-users, actionable in the field, consistent over time, and maintainable.
LCSI adopts an approach based on analysis of actual system operation, understanding of operational constraints, strict adherence to imposed references and sustainable information structuring.

Operating on sensitive programmes
Defence projects involve complex environments, high requirements, and supervised documentary processes.
LCSI is accustomed to operating in these contexts, adapting its methods to programme constraints, existing tools, and contractual requirements.
This adaptability is key in the defence sector.

Why LCSI operates in the defence sector
LCSI operates in the defence sector for one simple reason: documentation is a strategic issue, not a secondary deliverable.
Our value added is based on mastery of defence documentary frameworks, constant methodological rigour, proven expertise in technical illustration and interactive data management and a flexible organisation adapted to complex projects.
In the defence sector, documentation dictates system reliability. This is precisely where LCSI delivers its value.
