Which term in COA evaluation criteria refers to the ability to operate with other systems?

• A. Feasibility
• B. Interoperability
• C. Survivability
• D. Acceptability

Answer: (B)

Interoperability is about how well a course of action can operate with other systems, partners, and networks. In COA evaluation, it means the plan can exchange data, communicate, and coordinate with existing command-and-control, sensor, logistics, and partner systems. When systems use incompatible standards or formats, or can’t share information in a timely way, integration fails, which can derail execution. So this term specifically captures the ability to work smoothly across multiple systems and entities. By contrast, feasibility looks at whether the plan can be carried out with available resources, survivability focuses on continuing operations under stress, and acceptability concerns whether the outcomes are tolerable to stakeholders.
