When referring to people's skills, my (IT) circle sometimes refer to a person as being "fire and forget." This would indicate that you could tell such a person to accomplish a task, and they'd work it out themselves without constant supervision. The (to me) obvious etymology would be a fire-and-forget missile where the operator simply needs to target the weapon once as opposed to, say, a wire guided missile that requires needs to be manually guided to its target.
Is "fire and forget" widely understood in this context or is it just a geek thing?
