A sophisticated approach to negotiation

Founded in 1978, ENS was established with the core belief that the world would be a better place if everyone negotiated with the right mindset.
An understanding of human psychology and an effective negotiation process framework could change the way people view negotiations and the way they do business. They could achieve more than they thought possible.

I am a repeat offender. After having experienced in my previous company how much value we could generate from the ENS negotiation training, I am now leveraging ENS to drive change within SCHOTT Pharmaceutical Systems by developing a stronger internal and external influencing and negotiation culture.

Together with the Wittur Purchasing team, I've recently attended and enjoyed ENS “Negotiation and Influencing" workshop. Through interesting, intense and interactive sessions, we have learned useful tips and techniques for designing, preparing and delivering effective negotiations. The workshop was a mix of theory and hands-on practical learning. The trainer proved to be a real added value with his professionalism and ability to get everyone involved. ENS perfectly understood the challenges our organisation was facing and tailored a workshop to our needs and to ensure delivery of the particular targeted outcomes we wanted.
