What is technical documentation?
Manufacturers are obliged to provide technical documentation so that their products can be used safely. Technical documentation includes all documents necessary for a product (machine, system, device, software) to be used safely, comprehensively, and in compliance with regulations. This includes operating and user manuals, maintenance manuals, assembly instructions, transport instructions, spare parts information, and digital help systems.
For technical editors, one thing is clear: technical documentation is more than just a mandatory task. As a central component of the product, technical documentation builds trust, meets standards, and reduces risks. At the same time, it accompanies all documents throughout the entire life cycle of a product—from development to after-sales.
And depending on the type of product, the requirements increase significantly. Today, content must be available in multiple languages, can be updated quickly, and must be available on different channels—from classic manuals to interactive portals. The crucial question is therefore: How can technical documentation be designed to be efficient and future-proof?

Example of technical documentation and typical structure
Technical documentation comprises all documents that accompany a product throughout its entire life cycle—from development to after-sales. In most cases, the manufacturer is responsible for this documentation, which is often created by specialized editors who compile information from development, service, and product management.
Typical components are:
- Operating and assembly instructions: these describe how the product can be safely installed, commissioned, and used. More on the topic of creating operating instructions.
- Maintenance and service documents: these ensure the functionality of the product over many years.
- Safety and warning notices: essential for minimizing risks when handling the product.
- Installation and configuration instructions help to put products into operation correctly.
- Declarations of conformity and CE marking prove that the manufacturer meets the legal requirements for safety and documentation of its product.
- Additional digital content: such as online help or apps that supplement traditional manuals and documentation.
Specific example: Structure of technical documentation for a machine
An example of technical documentation in mechanical engineering could be structured as follows:
- Title page with product name and manufacturer information
- Introduction with intended use
- Safety instructions and hazard labeling
- Assembly and installation instructions
- Operating instructions
- Maintenance and service instructions
- Spare parts list
- Declaration of conformity
This example shows how technical documentation can be structured. The scope, structure, and content may vary depending on the industry, product type, and legal requirements. It is crucial that the documentation is complete, understandable, and compliant with standards.
Such instructions and documents ensure the correct use of the product and are often required by law. The challenge for creators is to prepare these documents for the target audience while complying with legal requirements and standards. The manufacturer is responsible for these documents. In practice, however, it is often specialized creators such as technical editors who compile information from various departments and prepare it in a consistent form.
Complete documentation helps to ensure that products are not only user-friendly, but also legally compliant and marketable.
Structure and content of technical documentation
Technical documentation thrives on a clear structure and comprehensible information modules. Only when the individual components are arranged logically and formulated consistently can users quickly find the information they need. The structure of technical documentation is based on fundamental principles that apply in almost all industries:
- Comprehensibility: Texts must be clear, precise, and formulated in a way that is appropriate for the target audience.
- Completeness: All safety-related information and use cases must be included.
- Legal protection: Depending on the product, laws, guidelines, and binding standards apply—for example, the Machinery Directive in mechanical engineering, the MDR in medical technology, or the Low Voltage Directive for electrical appliances.
- Modularity and reuse: Documentation modules should be designed in such a way that they can be used multiple times, maintained, and published in different formats.
- Target group orientation: Whether service technicians, end users, or administrators—each target group needs the information in a suitable form.
Depending on the industry and product, additional requirements may apply, e.g.:
- Mechanical and plant engineering: Operating instructions in accordance with the Machinery Directive with a clear definition of the intended use.
- Electrical engineering: Safety requirements in accordance with the Low Voltage Directive.
- Medical technology: Strict requirements in accordance with MDR, including formal criteria such as medium, readability, and adaptation to target groups.
- Software: Product liability law and, if applicable, data protection requirements.
In addition to these principles, there are typical components of technical documentation that may be supplemented or vary depending on the industry and product.
Example of the structure of technical documentation
An example of the structure of technical documentation illustrates how these principles can be implemented in practice:
- Title page & legal information – contains product name, manufacturer information, version number, and legal notices.
- Introduction & product overview – introduces the product, defines its purpose, and identifies the target groups.
- Safety instructions & warnings – summarizes sources of danger and explains protective measures.
- Operation & functional description – provides step-by-step instructions for installation, use, and operation.
- Maintenance & care – describes regular measures to ensure safety and longevity.
- Troubleshooting – provides support in diagnosing and rectifying typical malfunctions.
- Appendix – glossary, list of abbreviations, technical drawings, spare parts lists.
Good instructions are characterized by precise wording, comprehensible steps, and a logical structure. The result is documentation that is equally comprehensible, compliant, and practical—and thus meets the requirements of users, companies, and legislators.
Every company has its own requirements in terms of structure and information architecture. Our practical examples show how other companies are mastering this challenge.

Creating technical documentation: an overview of the steps
Good technical documentation does not happen by chance, but follows a clear process. A structured approach saves time, avoids errors, and ensures that the texts are understandable and reliable for all target groups. Complete documentation protects manufacturers from liability risks and supports CE marking. Editors use various tools to create technical documentation, from terminology management to an editorial system for technical documentation.
- Target group analysis – Before texts are created, it should be clear which target groups work with the product and what information they need. Each target group requires a different level of detail.
- Gather information – All relevant information comes from different departments such as development, product management, or service. The editorial team bundles this knowledge centrally.
- Define structure and layout – A consistent outline scheme forms the basis for understandable and reusable content.
- Consider standards and requirements – Legal requirements, industry standards, and internal guidelines must be complied with from the outset.
- Publication and distribution – The finished documentation should be made available in all required formats – from classic manuals to online help.
Practical tip: An XML editing system allows these steps to be mapped consistently – from modular content creation and standard-compliant workflows to automated output.
Who creates technical documentation? The role of technical writing
Behind every good piece of technical documentation is a well-coordinated editorial team. Creators of technical documentation are responsible for presenting complex information in a way that is understandable, complete, and compliant with standards for the respective target audience.
Their work involves more than just writing: they coordinate input from development, product management, and service, check legal requirements, and ensure that documents remain consistent across variants, languages, and product generations.
A modern technical editorial team works methodically and interdisciplinarily. Editorial teams create clear workflows, structure texts in a modular way, and ensure traceable quality with process reliability. In this way, editors contribute directly to product safety, customer satisfaction, and competitiveness.
Requirements & Standards in Technical Documentation
Standards and norms form the foundation of all technical documentation. The specific requirements that apply depend heavily on the industry, product, and target markets: While different regulations apply to mechanical engineering than to medical technology or software, additional national requirements come into play when exporting. At the same time, existing guidelines are evolving—especially with regard to digital formats and the exchange of intelligent information. The CE marking is only possible if the technical documentation meets the legal requirements, and manufacturers must ensure that their products are delivered with complete documentation.
Some key regulations include:
- IEC/IEEE 82079-1 – Core standard for instruction manuals
International basis for usage information. Since the 2019 revision, with a stronger focus on target group orientation, comprehensibility, digital media, and the qualification of editors. - VDI 2770 – Digital manufacturer information
Standardizes the structure and classification of digital documents, facilitating reuse and exchange – particularly relevant in complex systems and processes. - ISO 20607 – Mechanical engineering
Complements IEC/IEEE 82079-1 with specific requirements for risk presentation and safety instructions to make instructions in mechanical engineering legally compliant and comprehensible. - ISO/IEC 26511–26515 – Software Documentation
Guidelines for the creation, translation, quality assurance, and usability of software documentation – tailored to agile development cycles and international teams. - iiRDS – Intelligent Information Exchange
Modern standard for machine-readable, modular text modules including metadata. It is becoming particularly important in the context of Industry 4.0 and knowledge management.
This list is not exhaustive. In addition to those mentioned, there are numerous other industry-specific regulations – for example, on risk assessment, safety labeling, and online help. Companies should therefore regularly review their processes and adapt them to new developments in a timely manner.
The trend is clear: digital standards such as VDI 2770 and iiRDS are becoming increasingly relevant. Investing in structured, standards-compliant documentation processes today not only ensures legal compliance, but also creates efficiency and future viability.
Practical tip
Standards can only be implemented consistently in complex documentation projects if components are modular in design and managed centrally. An XML editing system such as COSIMA helps you to map workflows in accordance with standards, control versioning in an audit-proof manner, and output content in a media-neutral format.
Challenges in technical documentation
Anyone who creates technical documentation knows the challenges firsthand. On the one hand, information must be presented in a clear and user-friendly manner. On the other hand, legal requirements, guidelines, and internal processes must be complied with. In addition, there are industry-specific features that bring additional requirements. Many teams still work with isolated tools such as word processing or spreadsheets, which quickly reach their limits when it comes to complex documentation. A specialized content management system replaces these isolated solutions with integrated tools that work together seamlessly.
The most common challenges include:
- Time pressure: Product developments run in parallel, while the documentation must be ready by the delivery date.
- Multilingualism: Texts often have to be translated into ten or more languages – with tight deadlines and limited budgets.
- Versioning: Product changes lead to constant adjustments that must be implemented consistently across many documents.
- Complexity: Different target groups (end users, service, technical staff) require different types of documentation.
- Guidelines & standards: Specifications such as DIN 82079-1 or the Machinery Directive must be met, and errors can have legal consequences.
For technical writers, this means constantly balancing efficiency, precision, and legal certainty. Without clear structures and suitable tools, documentation quickly becomes a bottleneck.
Software for technical documentation
Technical documentation is not a peripheral task, but a central component of the product life cycle. Anyone who needs to provide content in multiple languages, variants, and formats will quickly reach the limits of traditional tools.
A modern editorial system not only supports the creation and management of documents, but also offers numerous functions that make everyday work easier: from automated workflows and version control to interfaces for translation and content delivery. Manufacturers with complex products in particular benefit from this because they can provide their documentation faster, more consistently, and in compliance with standards.
An XML content management system provides the methodological framework for this: workflows are clearly defined, responsibilities are transparently controlled, and legal requirements are reliably implemented. The result is documentation that can be created efficiently and maintained sustainably.
Why software is indispensable for technical documentation
Technical documentation is much more than just providing manuals. It serves as a knowledge base, legal protection, and service offering all at once. Without specialized software, however, editing processes come to a standstill: information is maintained multiple times, translations cost unnecessary time and money, and changes are difficult to track. Software for technical documentation creates structures that ensure efficiency, transparency, and future viability.
Advantages of specialized technical documentation software
The biggest advantage lies in modularization: components are created once and used many times. This reduces redundancies and increases consistency across all publications. Added to this are functions such as central management, flexible output formats, and support for standards in technical documentation. This not only gives companies speed, but also the assurance that their documentation remains up-to-date and reliable at all times.
XML editing system: The basis of modern documentation processes
An XML editing system combines technical standards with editorial methods. It enables the media-neutral creation of text modules that can be seamlessly published in various formats – from classic manuals to digital online documentation. At the same time, it maps workflows that ensure clarity within the team and compliance with regulatory requirements. Specialized software for technical editing combines methods, workflows, and tools that are specifically tailored to the requirements of the department. This makes it the technological basis for a scalable strategy.
