Train your teams on AI what works, what fails
Updated October 5, 2026 · 5 min read
Training a team on AI means teaching people to use it on their real tasks, with the tools the company approves and clear rules about data. What works: start from each person’s job, practice a little but often, and keep the skills current, because the tools change constantly. Since February 2, 2025, the EU AI Act has also asked companies to support their staff’s AI literacy.
Where companies stand: the numbers from France
In 2025, 18% of companies with 10 or more people based in France say they use at least one AI technology, according to Insee, the French national statistics office (Insee Première no. 2120, July 21, 2026). That is 8 points more than in 2024. The gap follows size: 15% of companies with fewer than 50 employees, 31% of those with 50 to 249 employees, 58% above that.
Among companies that do not use it, 71% say they do not see the point and 54% mention a lack of expertise. So the obstacle is not the tool. It is not seeing what it is for, then not knowing how to use it. Useful training addresses these two points, in that order.
What works
- Start from the tasks, not from the tool. An accountant wants to reconcile an account; a sales rep wants to prepare a meeting. Show what AI changes there: see the use cases for an accountant, a sales representative, or an HR manager.
- Choose one or two tools, and say so. One general-purpose assistant is enough to start: ChatGPT, Claude, Microsoft Copilot, or Gemini. Choose the one that fits your office software.
- Write down the rules about data. The French data protection authority (CNIL) recommends an internal policy that clearly states which uses are allowed and which are forbidden.
- Have people practice on real documents. A short session on a real set of meeting notes beats a general talk: everyone leaves with a prompt that works.
- Keep it current. The tools change fast: OpenAI has announced that ChatGPT’s custom GPTs will be retired on December 11, 2026. What is learned in January gets updated during the year.
What fails
- The one-off talk. A half-day awareness session with no practice: everyone goes back to their desk without knowing what to do on Monday.
- The same content for everyone. A beginner and someone comfortable with AI do not have the same needs. Neither do a lawyer and a salesperson.
- The tool bought without instructions. Licenses handed out without examples for each job: nobody knows where to start.
- The ban with no alternative. Without an approved tool, employees may well go through their personal accounts, outside any framework.
- The technique without the rules. Teaching people to write a prompt without saying which data never goes into one creates a risk.
What the rules ask for
The EU AI Act (Article 4), applicable since February 2, 2025 and rewritten in July 2026, asks companies that use AI systems to take measures to support their staff’s AI literacy, according to each person’s level and the context of use. It imposes no duration, no format, and no certificate: see the EU AI Act and AI literacy.
National employment law may add its own duties. In France, for example, the Labor Code (Article L6321-1) requires employers to adapt employees to their roles and to keep them employable, in particular as technologies change. As soon as personal data is involved, GDPR applies: see AI and GDPR at work. For a specific situation, see your lawyer or your data protection officer.

Frequently asked questions
Is AI training mandatory for companies?
In the European Union, yes, in a precise sense: since February 2, 2025, Article 4 of the EU AI Act has required companies that use AI systems to take measures to support their staff’s AI literacy. It sets no format, no duration, and no certificate.
How long does it take to train a team on AI?
No text sets a duration. Bet on regularity: a first session to set the rules and get a first use case right, then a little practice every week.
Does everyone need to be trained?
Article 4 covers staff who use AI systems on the company’s behalf, including, according to the European Commission, employees who write or translate with ChatGPT. The content adapts to the job, the level, and the risks of each use.
Which tool should we start with?
The one that fits your software: Microsoft 365 Copilot with Outlook, Word, and Teams, Gemini with Google Workspace, ChatGPT or Claude otherwise. Choose a team plan as soon as company data is involved.
Is Nova a training provider?
No. Nova is software, not an accredited training provider: it issues no diploma or certification. If you need a certified or funded course, go to a training provider.
