operational

adj

1. Of or relating to operations, especially military operations.

   “Private-equity nabobs bristle at being dubbed mere financiers.[…]Much of their pleading is public-relations bluster. Clever financial ploys are what have made billionaires of the industry’s veterans. “Operational improvement” in a portfolio company has often meant little more than promising colossal bonuses to sitting chief executives if they meet ambitious growth targets. That model is still prevalent today.”

2. Functioning and ready for use.

   “Princess Leia, before your execution, you will join me at a ceremony that will make this battle station operational. No star system will dare oppose the Emperor now.”

   “Despite somewhat faded paintwork, 87017 Iron Duke is clearly very much operational, as confirmed here on September 4.”

3. Effective or operative.
4. Determined by means of practical measures.
