The Full Operational Capability (FOC) is when a system is delivered to a user and they have the ability to fully employ and maintain it to meet an operational need. The mission capabilities of a FOC system are defined in a system’s Capability Development Document (CDD) and Capability Production Document (CPD).
Initial Operational Capability (IOC)
The Initial Operational Capability (IOC) is a point in time during the Production & Deployment (PD) Phase where a system can meet the minimum operational (Threshold and Objective) capabilities for a user’s stated need. The operational capability consists of support, training, logistics, and system interoperability within the DoD operational environment. IOC is a good gauging point to see if there are any refinements needs before proceeding to Full Operational Capability (FOC).
