1.
efficiently; deftly; in a well-organized manner
Doing something in a smart, organized way that gets good results without wasting time or effort.
Formed from 要領 (the knack; the key point) + よく (well). Describes someone who grasps the essentials quickly and acts on them without wasted motion. Can carry a slightly envious or even mildly negative connotation — implying someone is shrewd or cuts corners skillfully.
The opposite is 要領が悪い (to be bad at getting things done efficiently; clumsy in approach).
