Usability. I hate this word. Just another dispositional concept. Operationalism should be dead. For good. A serious thinker shall never convert a behavior into an essence. Like adaptability, intelligence, etc.
I prefer simplicity. It is not dispositional. Not all qualities are. Simplicity sure is essentialist. Use easiness if you consider simplicity is too metaphysical. Use any quality you like. A virtue is nice for an idea of perfection.
Seeking perfection can hinder when we see that what we're doing is not perfect anymore. We stop fighting. But it's the fight that is beautiful, not the product. Perfection seems too easy. There is no opponent.
