There's an element of creativity involved when you broaden the business deal and clarify the "it" you are negotiating.  A world-class salesperson looks for avenues to add value to the deal being negotiated.   

There are three very important rules in regard to creating value in a negotiation.  The first concerns the meaning of value itself, which is expressed as Value = Benefit - Cost. We've all, of course, heard about sales processes that are supposed to add value but hardly ever succeed in creating real, measurable business value. A strategic negotiation process does succeed though, because it enables you to add "hard" value (value you can measure) rather than "soft" value.  If you can't put a potential trade through the equation above, you're not creating value.

The second rule is Never concede - always trade. If you simply concede on an item during a negotiation, you are eliminating the possibility of creating value because value is created by trading items that have differing importance to the two sides in a business negotiation.

The third rule is Never negotiate one thing by itself.  If you negotiate one item at a time, you will soon find that you don't have any other items with which to trade.  If you can't trade, you can't create value.
