Strategy was a planned method for dealing with an issue.
In 2366, Jean-Luc Picard noted in his captain's log that "With confirmation of the Borg's presence in Federation space, Admiral Hanson has returned to Starbase 324 to discuss strategy with Starfleet Command." (TNG: "The Best of Both Worlds")
In 2375, befuddled by the idea that the crew of the USS Voyager had taken on a new Borg drone, One, following having done the same with Seven of Nine, B'Elanna Torres sarcastically suggested that it was the Borg Collective's new strategy: that rather than assimilating people, they instead simply showed up and looked helpless. (VOY: "Drone")
