the operator then uses this information to test the new component. If the
test is successful, the component is deployed, but otherwise it is corrected and
tested again.
6.3 Relationship with Other Viewpoints
The technology viewpoint is primarily related to the engineering viewpoint
because it specifies the hardware and software components that have to im-
plement the engineering objects, including the nodes and channels identified
in the engineering specification. Thus, there is a technology object corre-
sponding to every atomic or composite engineering object. Note that the
relation goes both ways: engineering objects provide the entities that need
to be implemented, and technology objects provide the information on the
specific technology used to implement them and the standards to which these
implementations should conform.
