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.
