The IRRE® model
The IRRE® model was developed by Angelika Schulz-Fuss. She studied in Canada under the tutelage of Glen Whyte, PhD, one of North America’s most respected professional negotiators, and learnt the art of professional negotiation based on the Harvard model.
In the IRRE® model, she combines professionally learnt negotiation skills with her expertise in systemic, neurosystemic and hypnosystemic contexts, thereby creating a practical model that’s effective and easy to understand. She has been teaching this model to individuals in management, purchasing, sales, project management and other areas for 20 years now.
The name “IRRE®” is derived from the first letters of the four main influencing factors that determine whether you’re going to experience success or defeat in a negotiation:
Intellect – Result – Relationship – Emotion.
How does it work?
Two ways you can learn about how it works are seeing it being used in practical situations in our IRRE® training courses and reading about it in the IRRE® book!
Testimonials
One of the best, if not the best, negotiation trainings available for both buyers and sellers! Thanks to its strong practical relevance and the excellent way in which the necessary theoretical knowledge is conveyed, this seminar comes with my highest recommendation!
As Vice President Procurement and Supplier Management at a global enterprise, I’ve worked with many negotiation frameworks. The IRRE® model clearly sets itself apart. It combines neuroscience, psychology, and practical tools into a highly effective approach. It makes visible how emotions, mental hierarchies, inner proportions, and internal states influence negotiation behavior—something many conventional models ignore. What I value most is its focus on creating lasting, mutual value instead of just short-term wins. Training alongside departments like Sales brought new perspectives—and helped us better understand each other’s realities and constraints. In procurement, we tend to think rationally. But in the real world, deals often fail on the emotional or relational level. IRRE® helps structure those “soft” factors, guides communication with intent, and builds genuine connection. The payoff: stronger outcomes, even when facing pushback. On top of that, IRRE® complements existing methods and adds a distinctive, neuroscience-based layer to any negotiation toolkit.
Rethinking Negotiation – Effective. Sustainable. Impactful. With years of experience in sales, I believed I was well-versed in negotiation strategies and techniques. I was wrong. IRRE® offers a fundamentally new approach: authentic, clearly structured, and immediately applicable. What sets it apart is its impact beyond the business environment – it actively supports personal development, both professionally and privately. IRRE® enables negotiation partners to jointly develop robust, distinctive solutions. For anyone who wants to not just conduct negotiations, but truly understand and master them, this model delivers real value.
Participating in the “IRRE Negotiation” seminar with Angelika Schulz-Fuss significantly elevated my negotiation capabilities. I now approach negotiations with structured preparation, strategic clarity, and heightened awareness in communication. The IRRE® model – encompassing Intellect, Relationship, Result, and Emotion – proved to be a practical and powerful framework for navigating complex negotiation dynamics. The seminar’s integration of theory, applied exercises, and neuroscientific insights provided both actionable tools and a deeper understanding of decision-making processes. A clear recommendation for professionals aiming to move beyond transactional deals and achieve sustainable, value-driven outcomes.
The seminars are characterized by their practical effectiveness. They adeptly illustrate and provide a tangible experience of the principles governing effective negotiation. At Umdasch Store Makers, Mrs. Schulz-Fuss successfully united employees from diverse cultural backgrounds in pursuit of margin enhancement within project operations, all while keeping the fundamental customer benefit in mind.
Angelika Schulz-Fuss is a fascinating personality who is captivating in her presentation. This succeeds through her personal performance and many surprise elements that she incorporates. She senses the audience and answers questions with depth - I appreciate this quality very much.
An excellent training course that points out options you would never think of otherwise. All the information can definitely be put into practice and there are lots of interesting contributions from real-life negotiation situations. Professional with lots of helpful tips.
Thank you very much for an extremely interesting and informative seminar. It is good to learn about new approaches to finding a solution that are not just motivated by a selfish desire to reach your own goal, but show how added value can be created by joining forces with the other party. And this is all done with a positive basic attitude. This also makes me want to approach negotiations and similar situations more positively and create benefit for all the parties involved.
Even after nearly thirty years of working in sales, you can still be surprised! Many sales coaches are replaceable, but not Angelika Schulz and her IRRE® coaching. She delivers her content in a refreshingly charming, highly professional and extremely competent manner.
The IRRE® model shows clearly how many options there are in solution-oriented negotiations when you are negotiating on an equal footing. The model is easy to internalise, meaning anyone can adopt it quickly.
My colleagues and I were really impressed with the "IRRE® Negotiation" seminar! It differs from "conventional" sales seminars, because it is practice-oriented and its content genuinely can be applied to our daily work processes. We have certainly adopted "selling by asking questions and not by arguing" as our main sales strategy.
Angelika Schulz-Fuss conveyed to us participants in a very authentic way that parties have to be on an equal footing and have genuine appreciation for each other when negotiating if they want to build successful partnerships.
Angelika Schulz-Fuss is a successful coach who shows how the IRRE® model will deliver phenomenal results for every single negotiating party who adopts it.
