EU AI Act – Definition, Use Cases and Best Practices at a Glance
The EU AI Act is the European legal framework for the development, provision and use of AI systems. It follows a risk-based approach in which obligations rise with the risk of the respective AI application.
EU AI Act: Definition & Meaning for AI | Glossary
Companies using AI no longer operate in a legal vacuum. For the first time, the EU AI Act creates a uniform European framework for which AI applications are permitted and which obligations come with them.
For companies this does not mean standstill but clarity: those who cleanly document use cases, data, roles and controls can use AI responsibly and traceably – and avoid nasty surprises.
This glossary entry for EU AI Act gives you a clear Definition, practical Use Cases and Best Practices at a glance – with examples, pros and cons, and FAQs.
What is EU AI Act?
- EU AI Act – The EU AI Act is the European legal framework for the development, provision and use of AI systems. It follows a risk-based approach in which obligations rise with the risk of the respective AI application.
The EU AI Act is a regulation of the European Union that governs the development, provision and use of AI systems. At its core is a risk-based approach: AI applications are classified into risk categories according to their potential harm, and obligations rise with risk.
Applications with unacceptable risk are banned, high-risk applications face strict requirements for transparency, risk management, data quality, human oversight and documentation, while low-risk applications have far fewer obligations.
For companies this means concretely: they must know and document their AI use cases, the data processed, the roles involved, the responsibilities and the control mechanisms. The EU AI Act is closely connected to data protection (GDPR), information security (e.g. ISO 27001) and internal audits.
This glossary entry does not replace legal advice but frames the topic for project practice.
How does EU AI Act work?
In practice, engaging with the EU AI Act starts with an inventory: which AI systems are in use or planned, and which risk do they fall under. For each use case, purpose, data sources, affected individuals and possible impacts are considered.
From this follow the obligations to meet – such as transparency towards users, human oversight for critical decisions, risk management, data quality requirements and traceable documentation. A clear distribution of roles and responsibilities between the provider and the operator of an AI system matters.
Governance structures, staff training and integration with existing data protection and security processes accompany this. AI use thus becomes not only compliant but also trustworthy and controllable.
Practical Examples
Before introducing AI-assisted candidate screening, a company checks whether it is a high-risk application and which obligations follow.
For an AI chatbot, it is ensured that users transparently recognise they are communicating with an AI.
For an AI system with decision support, a human control instance is set up for critical cases.
A company documents data sources, responsibilities and controls of its AI applications to establish accountability.
As part of an AI rollout, governance, training and data protection are considered from the start.

Frequently Asked Questions about EU AI Act
What does the EU AI Act regulate?
The EU AI Act governs the development, provision and use of AI systems in the EU with a risk-based approach. The higher an application's risk, the stricter the obligations – up to a ban on certain applications.
Does the EU AI Act also affect mid-sized companies?
Yes. As soon as a company develops, provides or uses AI systems, obligations may arise depending on the use case and role. It is important to know and classify one's own AI applications.
What is the risk-based approach?
AI applications are classified by their potential for harm. Low-risk applications have few obligations, high-risk applications strict requirements for transparency, oversight, data quality and documentation, and some applications are banned.
What concretely must companies do?
They should know and document their AI use cases, data sources, roles, responsibilities and control mechanisms, build governance and integrate AI use with data protection and security. A precise classification often requires technical and legal support.
Is this entry legal advice?
No. This glossary entry frames the EU AI Act for project practice but does not replace individual legal advice. For specific obligations in individual cases, legal review is required.

Look beyond isolated technical merits
When you judge whether EU AI Act is the right fit, look beyond isolated technical merits. You should weigh the full project context.
Consider the following factors:
- Existing team expertise
- Current infrastructure
- Long-term maintainability
- Total cost of ownership (TCO)
Drawing on our experience from over 250 software projects, we have found that correctly positioning a technology or methodology within the broader project context often matters more than its isolated strengths.
