What does 'Operational Availability' measure in systems acquisition?

Operational Availability measures the readiness of a system to perform its required functions whenever needed. This concept is crucial in systems acquisition because it reflects not only the operational state of equipment but also encompasses factors such as maintenance, logistics, and downtime. High operational availability means that a system is reliable and can be relied upon to be operational when required, which is essential for mission success.

Operational Availability takes into account various elements, including repair times, maintenance schedules, and supply chain effectiveness, but its primary focus is on the system's overall readiness for use. It is particularly important for military operations, where the timely availability of systems can have a direct impact on mission outcomes. This is why emphasizing the readiness to perform required functions captures the essence of operational availability within the context of systems acquisition.
