Joint realization
At this point, our next step is joint realization. If we think of an individual operation
in the system, at any level of decomposition, it has a tie to both its logical
element, and to the distribution element where it is implemented. An analogy
would be a person who is a citizen of one country, but a resident of another. The
operation is a citizen of its logical element, where it was
born and had its origin in
the model. The same operation is a resident of the locality where it has been
implemented; where it now
lives and performs its work.
