R3S standards should be evaluated
for each 4 years to decide if necessary
to update or delete. There are two important
factors to make decisions for
update and deletion: the first is feedback
received from tailoring process in application
of standards; the second is
number and importance of change requests
received in four years.
Users of standards usually will make
tailoring on standards in order to adapt
their requirements. Tailoring results are
basic and important information for
standard evaluation.
In addition to feedback in tailoring
process, users shall be encouraged to
provide change requests for modification
or delete of exiting standards, also
for developing new standards based on
their requirements or new emerging
technologies and processing.
In summary, R3S standards develop-ment
from start, through publishing, to updating is a process of
evolution. This evolution process is standard lifecycle, as shown in
Table 1.
In the lifecycle of a standard, the message flow is shown in Fig. 11.
Conclusion
This paper describes the importance to establish RSCO space standard
system. Two concepts of the system are compared and up to the
fourth level of system breakdown were provided. The detailed process
of developing standards is illustrated. Limited by pages, a complete
list of standards, discussed. Some important issues, such as how to
make tailoring in application of standards and strategic cooperation
with other standard organizations, could not be given and discussed
with this page.
