Negotiation is all about sharing.  

Well, at least pretty much all about sharing. One of the big questions  that every negotiator is dealing with when we start a negotiation is just exactly how much we want to share with the other side.  We all know that no matter what negotiation styles or negotiating  techniques we use, we are going to have to share at least some  information with the other side. The question that we are facing is how  much is too much? 

Negotiators need some guidance in how to go about  doing this sharing thing the correct way.
