5. Interoperability Key Performance Parameter (I-KPP)
a. ORD interoperability KPPs, and hence the IERs that the
interoperability KPPs are derived from, will be measurable and testable.
b. Top-level IERs will be used as the basis to develop
interoperability KPPs. The I-KPP interoperability KPP definition will
include that all top level IERs will be satisfied to the standards specified
in the threshold and objective values.
c. Typically the threshold criterion for the interoperability KPP
will be 100 percent accomplishment of the critical top-level IERs, and the
objective criterion for the interoperability KPP will be the accomplishment
of all top-level IERs.
d. If a time-phased evolutionary or block approach to stating ORD
requirements is being used, the ORD should identify a separate
Interoperability KPP for each phase or
