The correct answer to this open question is the following.
Conduct a meeting with the client about negotiating.
I choose to write about the scenario.
In this meeting with my client, I am going to provide him with important tools to improve his negotiation skills so he can get better deals for his company.
I would create the scenario in which I will be the other part he is about to negotiate with. For this to happen, I am going to explain some basic principles about negotiation and put a series of examples so he can grasp the most important ideas.
Secondly, I am going to share a handbook, or better said, a manual with important key principles of negotiation that could serve him as a guide so he can feel more confident during the negotiation process.
Finally, we are going to have at least thirty minutes to practice a real-life negotiation scenario. It is going to be something basic but real so my client can face some adversity since the beginning of the negotiation process so he can have a good idea of the importance of being fully prepared before entering the negotiating table.
