If you don't have the ability to near-instantaneously "spike" your production to meet demand, then you have an opportunity for arbitrage. At least a time-based one. Additionally, if you do have over-abundant capacity to pre-manufacture well above that required "spike", then you need to a) use logistics to get it there and b) foresight of knowing where you need to get it to, and how much of it. Otherwise, you'd have to have the ability to produce any arbitrary amount of it at the desired location when the need requires. By it, I generally mean all products.
