  • In attendance
  • Certifiable

The Expert Masterclass is the third step in the full training process. It can only be applied for if the participant has completed the Advanced course. In this Masterclass we will go through analyzing the credibility of threats and ultimatums, managing difficult profiles, relying on intuition, confidence in the team, the capacity to thwart maliciousness, strategic questioning, managing dilemma or the capacity to get the upper hand in any situation. 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.




  • Analyse the credibility of threats and ultimatums
  • Neutralise difficult profiles
  • Make informed decisions
  • Reverse the balance of power
  • Get the upper hand in any kind of negotiation
  • Conduct a difficult debriefing
