EVAMOSC

Managed by the Office of the Secretary of Defense, Cost Assessment and Program Evaluation (OSD CAPE) in collaboration with the Services, EVAMOSC brings together sustainment cost data from across the DoD into a unified system.

            indicating system performance and customer satisfaction.

The data in EVAMOSC will not only address capability gaps in the cost community, but will also be useful in program review, readiness planning, and the acquisition community.
