Technical documentation

Design, structure and transmit product information

Technical documentation covers all documents required for the use, maintenance and operation of a product or piece of equipment.

​

LCSI supports industrial companies in the creation of compliant technical documentation tailored to real-world use, throughout the entire product lifecycle.
Our approach is to make technical information immediately usable by operators, technicians, maintenance teams and end users.

What is technical documentation used for?

Technical documentation is not limited to describing a product. It enables companies to:

​

  • ensure safe use of equipment,

  • secure maintenance operations,

  • reduce human error,

  • facilitate onboarding and training,

  • meet regulatory requirements

  • preserve and transfer technical know-how.

​

In industrial, railway or defence environments, documentation quality directly impacts operational performance.

Documentation adapted to products, users and operational contexts

Each document type serves a specific purpose. LCSI designs technical content adapted to the level of technical complexity, usage conditions and sector-specific constraints.

Instructions manuals

Instructions manuals define how machines must be used safely. They are written in compliance with Machinery Directive 2006/42/EC and the EU Machinery Regulation 2023/1230, and are primarly intended for industrial equipment and special-purpose machines.

User manuals

User manual explain how equipment works in a clear and accessible way. They are designed for industrial or consumer products, taking into account user profiles and real usage conditions.

Maintenance manuals

Maintenance manuals describe preventive and corrective maintenance operations. They include procedures, diagnostics, task sequences and maintenance plans, and are widely used in industry, railway and defence sectors.

Spare parts catalogues

Spare parts catalogues facilitate the identification and ordering or components.

They rely on exploded viewx and structured parts lists, available in PDF or interactive formats, and are essential in many regulated sectors.

Technical illustrations and diagrams

Technical illustrations play a key role in the immediate understanding of procedures or maintenance sequences. They are used for technical support, training and product communication.

Technical 3D animations

3D animations make it possible to visualise complex mechanisms, procedures or maintenance sequences. They are used for technical support, training and product communication.

Training materials

Training materials support the development of operator and maintenance team skills. They are delivered in various formats: training documents, presentations, e-learning modules or videos.

Documentation production designed for industry

LCSI supports technical documentation projects:

01

Creation or complete overhaul of existing documentation

02

Updates linked to product evolution

03

As a complement to other service providers

04

For single projects or large documentation volumes

Nous intégrons dès la conception les contraintes réglementaires, les exigences normatives, la structuration des contenus, la cohérence entre documents et la maintenabilité dans le temps.

Entrust your technical documentation to LCSI

Well-structured technical content helps to improve safety, redure operating costs, speed up interventions, facilitate training and secure product information.

​

For over 30 years, LCSI teams have supported industrial companies in structuring and producing technical content. Our value lies in a deep understanding of products, operational constraints and real-world usage, combined with strong expertise in illustrating equipment operation and maintenance.

Industries we support

Our technical documentation expertise applies to many sectors:

Industry and special-purpose machinery

Railway sector

Defence

Medical equipment

Consumer products

Electronics

Software and embedded systems

Field expertise

Our engineers, technical writers and project managers work directly from operational realities:

Technical data and drawings

Digital mock-ups and 3D models

Funcional specifications

Field

feedback

Operating and maintenance constraints

Regulatory and normative requirements

This approach transforms complex information into structured technical content that is directly usable by end users.

Proven methods

Each technical documentation project is structured according to your operational challenges, including delivery timelines, documentation volumes, required technical depth, applicable regulatory constraints and product evolution.

​

LCSI integrates seamlessly into your organisation, working remotely or on site, to secure deliverables and ensure smooth collaboration with your technical teams.

A flexible, results-oriented organisation

LCSI is a human-sized organization, designed to adapt quickly to project constraints and complex technical environments.

​

This structure enables high responsiveness during scoping and production phases, short decision-making loops, rapid adaptation to product or regulatory changes and smooth collaboration with client teams.

​

This operational agility is a concrete advantage compared to heavier organisations, especially on demanding, time-constrained technical projects.
