Comparing Efficient, Effective, and Proficient

Adjective

These three words cover some overlapping territory.

Efficient most often describes what is capable of producing desired results without wasting materials, time, or energy. 

While the word can be applied to both people and things, 

it is far more commonly applied to things, 

such as machines, systems, processes, and organizations. 

The focus of the word is on how little is wasted or lost while the desired results are produced.

Effective, typically describes things

—such as policies, treatments, arguments, and techniques

—that do what they are intended to do. 

People can also be described as effective 

when they accomplish what they set out to accomplish,

but the word is far more often applied to things.

Proficient typically describes people, and it often is followed by the preposition at.

If you are proficient at something, you are very good at it. 

You are, in fact, so good at doing it that you are unusually efficient when you do it.

One can also be proficient in something, such as a language.
