When determining which task will be performed, the column with a match in the farthest
right hand column will indicate which process development takes precedence. However, the
appropriate Equipment/System Manager will make the final determination based on all
factors.
The Coast Guard Mission Criticality Code (MCC) indicates what impact on the mission
capability of the cutter/unit would result should a configuration item fail. The code is assigned
to a weapon system or end item in a specific shipboard/shore unit to denote its importance to the
mission of the unit in which the component is installed. The MCC of equipment is an indicator
of the importance of that equipment to the missions of the unit.
IMPACT
MCC
1
Failure of component /equipment causes minor mission impact or partial loss of
secondary mission.
