Complex negotiation – Advanced

  • In attendance
  • Certifiable

The Advanced Masterclass is the second step in the full training. It can only be applied for if the participant has completed the Essentials training course. Some of the things we will cover in this Masterclass are managing cognitive overload, the advanced motivations of the opposing party, managing complex profiles, advanced strategies, negotiating as a team, releasing stress, advanced influence techniques, behavior analysis and different ways of debriefing. This Masterclass subtly alternates between a theoretic approach and both individual and group role-playing.


The Masterclass is for any person who must negotiate at their work or in their specialized field, regardless of their level.




  • Understand your point of contact beyond words
  • Get to grips with advanced strategies
  • Conduct any kind of negotiation
  • Manage complex profiles

"ADN’s Masterclasses are unlike any other training course in negotiation. I have been doing sales negotiation for over 20 years, but I never experienced anything as powerful as the moments I had during the 2 Masterclasses I was lucky enough to participate in."
