La formation avec Adrien était super! Merci à toi pour ton implication !!

Camille Bezes
Client testimonial

Aanrader, fantastisch waardevolle workshop om een impactvolle onderhandelaar te worden. Goede balans met informatie ontvangen en zelf aan de slag gaan dmv een case. Adrien weet precies op het juiste moment er een case in te gooien, wanneer je merkt dat je even inkakt bijv na lunch. Heel waardevol dat je wordt opgenomen op video en dit samen met de groep te analyseren. Daar gaat veel tijd in zitten, maar is heel leerzaam. Goede manier om je bewust te zijn van je verbale en non verbale gedrag, en hoe te verbeteren.

Zeer goede en professioneel opgezette negotations course vevolgd. Er is veel focus op het in praktijk brengen van theorie, met tal van oefeningen die verrassen en je scherp houden. De trainers putten uit jarenlange ervaring, waardoor ze veel aansprekende voorbeelden delen. Hierdoor komt de training echt tot leven. Je leert je eigen sterktes en valkuilen begrijpen, en na afloop ben je equipped met goede frameworks en methodes die je onderhandel-skills naar een nieuw niveau tillen. De combinatie met scherpe ‘on-the-job coaching’, zorgt ervoor dat je veel meer waarde uit je onderhandelingen gaat halen. Dat maakt het een top investering, die zich blijft terug betalen!

Google Review ★★★★★

De onderhandelingstraining die ik volgde, was een echte eyeopener. Praktisch, scherp en direct toepasbaar. Theorie en praktijk kwamen perfect samen dankzij interactieve opdrachten, waaronder 1-op-1, 2-tegen-2 en groepssessies.De trainer was een ervaren professional die duidelijk de klappen van de zweep kent. Geen abstracte modellen, maar echte situaties waarin je wordt uitgedaagd om beter te luisteren, strategischer te denken en bewuster te handelen.Onderhandelen is een zwaar ondergewaardeerde skill, terwijl het zó bepalend is voor commercieel succes. Deze training bewijst dat onderhandelen absoluut te trainen is – en hoe!Kortom: een must voor elke commerciële professional die zijn of haar impact wil vergroten.

Formation de négociation de trois jours avec Adrien vraiment top!Le contenu était non seulement complet et pertinent, mais il était également réalisé de manière dynamique et interactive. J’ai beaucoup aimé le format : nous avons exploré des stratégies de négociation dans des contextes variés, et cela m’a donné une vision beaucoup plus large de l’art de la négociation. De plus, l’ambiance de groupe était très sympa, ce qui a rendu l’apprentissage encore plus agréable.J’ai beaucoup appris en 3 jours, et je me sens désormais beaucoup plus confiante pour mes futures négociations.Je recommande vivement cette formation avec Impact Negociation Group !

Ik was positief verrast door de manier waarop Adrien gedurende de twee dagen de deelnemers wist te inspireren. Hij slaagde erin om een perfecte balans te vinden tussen het delen van theoretische kennis en het toepassen daarvan in praktijkgerichte oefeningen. Wat het extra waardevol maakte, was de structurele feedback die hij steeds gaf na de oefeningen, waardoor je echt kon groeien in je onderhandelingsvaardigheden.Adrien’s ruime ervaring als onderhandelaar gaf de workshop veel diepgang. Hij wist steeds treffende voorbeelden uit de praktijk te geven, wat de theorie levendig en concreet maakte. Dat maakte de workshop niet alleen leerzaam, maar ook bijzonder boeiend.Ik zou deze workshop aanraden aan elke professional, van jong tot senior, die zijn of haar onderhandelingsvaardigheden naar een hoger niveau wil brengen. Een absolute aanrader!

Go for it. Collectively. Each individual can find bits that are useful no matter each person’s knowledge or expertise. On top of it you are creating a « discussion language » shared by all that will facilitate future discussions.
