Colleagues, clients and directors decide based on the situation they're in, not on your arguments. In two days you learn to read that situation and design it. You gain more influence on what they choose, even when you are not their boss.
For advisers, project leads, policy makers, account managers and managers who need to get others on board without being their boss.

Influence is the ability to change what another person chooses and does. Without formal authority, you gain influence through the situation in which the other person decides: what they see, what others do, how much effort a choice takes and what risk they feel. Learning to read and design that situation is the skill of influencing choices and behaviour. More influence is the result.
More on the method: the SUE Influence Framework.
You backed the proposal with numbers. The director says "interesting" and it disappears into a drawer.
The client was enthusiastic in the meeting. Then you hear nothing more.
Your colleague from the other department says yes in the meeting and then simply works around you.
A standard influencing course teaches you to talk better. But your story was never the problem. The problem is the situation in which the other person decides.
Programme, dates, price and what you take home, in one PDF you can also forward to your manager.
You see which fears and habits hold the other person back, even when they do not name them themselves.
You stop rewriting your pitch for the tenth time. You design the moment the other person decides.
You use social proof, friction and framing on purpose. And you spot it straight away when someone uses them on you.
People come along, even though you're not their boss. They don't feel played, because they choose for themselves.
You learn this with Behavioural Design and the SUE Influence Framework: first understand why someone is not saying yes now, then design the situation in which they do.
A maximum of 16 participants. Both days you work on someone you really need to win over right now. So no textbook case.

Super, I got clear and practical guidance on Behavioural Design. It's never a one trick pony.

In two days we got the basics of how to apply Behavioural Design in practice. Astrid can convey the importance of outside-in thinking in a clear, informative and interesting way. I now feel like applying this in my own daily practice.

Does your whole team need to bring stakeholders along? Then the two-day Sprint at your location is the format.
By changing the situation in which the other person decides, rather than arguing harder. Find out what they want to achieve, what worries them and what ties them to the old habit. Then make the choice you propose easier, more visible and less risky. That works with colleagues, clients and directors who do not report to you.
Start with one concrete decision you need from someone. Describe the behaviour you want to see and the moment that choice is made. Then look at what holds the other person back at that moment. Do that a few times and you are practising the skill of influencing choices and behaviour, and your influence grows with it.
How people really decide, how to map what drives and what holds back the person in front of you, and how to design and test interventions. For two days the person you need to bring along is your case, and you go home with a toolkit you use the following week.
Influencing without authority is getting people to choose what you propose when you're not their boss. Better arguments barely help. What matters is the situation in which the other person decides: what they see, what others do, how much effort it takes and what risk they feel. In the training you learn to read and design that situation.
Both. Persuasion is about what you say. Influencing is about the situation in which the other person decides. You learn both, with the emphasis on designing the decision. Because that works even when you're not in the room.
For advisers, project leads, policy makers, account managers and managers who need to bring others along without hierarchy. No background in psychology required.
Two consecutive days in Amsterdam, a maximum of 16 participants. English-language editions run several times a year. The next date is at the top of this page, and you'll find every date on the training page.
€ 1,490 excluding VAT, including the Behavioural Design Toolkit, lunch, the EQAC certificate, the AI Mentor after purchase and lifelong membership of the BD Club.
No. Manipulation works against the interest of the other person and stops the moment they see through it. Behavioural Design makes it easier for people to choose what they already want. We talk about the ethical line openly in the training.
Yes. For teams there is the Sprint: the same two days at your location, with your own case, for 5 to 24 participants.
