What does operational mean?
Operational describes something connected with the practical work of running an organization, system, process, or activity. It commonly suggests that something works effectively and is ready for use: an operational system, operational costs, or an operational plan. In military and institutional contexts, the word can refer to the actual execution of activities rather than planning or theory. “Operationally” is its standard adverb, as in “operationally effective” or “operationally ready.” The term is widely used in business, technology, government, healthcare, and the military. It is often more specific than simply “practical” because it implies an activity, process, or system in operation, and it is more concrete than “effective” when referring to readiness or day-to-day functioning.

A word can be perfectly operational without being glamorous: it simply works, and keeps working.
