I think this is a good observation. The term 'scrum' appears to have been applied to s/w development by someone unfamiliar with software, rugby, or both.
Or perhaps it was coined by someone with a wicked sense of humor who was spot on with an analogy describing the butting of heads while the object (the ball, or the code) sits unmoved. And the term was sold to the PHBs with exactly this hidden meaning in mind. And management hasn't got the joke yet.
