Innovation was the process of taking an idea or solution from inception to impact. An individual who had innovation was called an innovator.
In 2373 during the Q Civil War, Q was injured by Q weapons which were perceived as cannonballs and lead charges. Kathryn Janeway didn't think that a Q could be injured, but Q told her that she would be surprised what innovative munitions could be created by one immortal being who set their mind on killing another.
