IOT&E

Initial Operational Test and Evaluation

What it actually means

The formal operational test of production-representative systems, run by an independent test agency with real operators under realistic conditions, that informs the full-rate production decision. It answers the two statutory questions — operationally effective? operationally suitable? — and its report goes places program offices can't edit.

Where you'll meet it

The gate between low-rate and full-rate production on major programs.
