Know how to recognise and define elements of a negotiation that cannot logically be separated from one another even though they may be physically or conceptually separated.
Elements, items or concepts, that rely for their value to a party on an association with another element may not be sensibly (logically) separated. To separate such elements would be to remove their value in a negotiation. Therefore such elements should be considered as one. In some cases an element may give value to more than one other element. In such cases it may be necessary to group such elements to maximise overall negotiated value.
The knowledge named 'Identify logical inseparable elements' is considered to be very important.
In addition, the knowledge is thought to be of average complexity but quite difficult to learn, it is learned mainly by experience but needs study, and is modelratley specialised knowledge.
Opinion is that it is practically justifiable knowledge.
