The phrase "be found wanting" means to be insufficient or inadequate in some way, falling short of expectations or requirements. Some antonyms that could be used to describe the opposite of being found wanting include "exceeding expectations," "meeting requirements," "meeting or exceeding standards," "successful," and "satisfying." These words all suggest that something or someone has done a good job of fulfilling their responsibilities or meeting the demands placed upon them. By contrast, being found wanting can imply that someone or something has failed to live up to expectations, perhaps suggesting that they need to improve in some way in order to meet the required standards.
