Know how to identify component parts or elements of a negotiation.
Things that can be isolated can be discussed within a negotiation and traded if necessary. Some things are not useful unless accompanied by other things, it may be unwise to consider such elements separately. Separable elements are things that can have value to one or other party in isolation or can increase or decrease negotiated value for that party.
The knowledge named 'Identify basic components' is considered to be rather important.
In addition, the knowledge is thought to be quite simple and mostly easy to understand, it is generally learned by study, and is largely generally used knowledge.
Opinion is that it is fairly justifiable knowledge.
