Initial operating capability or Initial operational capability (IOC) is the state achieved when a capability is available in its minimum usefully deployable form. The term is often used in government or military procurement.
Declaration of an initial operating capability may imply that the capability will be developed in the future, for example by modifications or adjustments to improve the system's performance, deployment of greater numbers of systems (perhaps of different types), or testing and training that permit wider application of the capability.
