Compromise is one technique in doing optimization: as someone mentioned, you could be maximizing a known good property of your product with no ill-effects on any other property. But you might be optimizing an overall experience for two needs, which means balancing potentially conflicting goals, and choosing imperfect solution for both — some might use the term "compromise" for this.

Other terms are in use, like "balance" or "trade-off" from the OP or... But I believe the message is clear in that the OP believes majority of design is about balancing opposing forces and their tension and they call that compromising.
