there's 'reasonable effort', 'commercially reasonable effort', 'best effort', etc. these are all legal terms that are commonly used, but are still a little vague. my read (and ianal) is that if a company has a hard contractual obligation to fill an order, they need to do that first and then can make a 'best effort' to fill the other orders. best effort is effectively lower priority than an actual contractual obligation.
