  • critical operational issue

    COIs are key operational effectiveness or suitability issues that must be examined in operational test and evaluation to determine the system's capability to perform its mission. COIs must be relevant to the required capabilities and of key importance to the system being operationally effective, operationally suitable and survivable, and represent a significant risk if not satisfactorily resolved. A COI/COIC is normally phrased as a question that must be answered in the affirmative to properly evaluate operational effectiveness (e.g., “Will the system detect the threat in a combat environment at adequate range to allow successful engagement?”) and operational suitability (e.g., "Will the system be safe to operate in a combat environment?). COIs/COICs are critical elements or operational mission objectives that must be examined, are related to Measures of Effectiveness (MOE) and Measures of Suitability (MOS), and are included in the Test and Evaluation Master Plan (TEMP).
