Maintenance in operational condition, MCO, includes two activities, namely technical support and logistical support. These two MCO activities can be and are directly impacted by two increasingly present phenomena: obsolescence and shortage. Long ignored, obsolescence and shortages worsen the unavailability of systems, immobilized or in degraded operation following breakdowns or for reasons of preventive maintenance. The objective of this article is to analyze the links between MCO and the management of obsolescence and shortage. It is argued that, from now on, the MCO must systematically include an effective and efficient management of obsolescence and shortage in order to be able to accomplish its main mission. This modified MCO paradigm is modeled by an actigram structuring these links.
