Have you ever thought about the difference between effective and efficient?
EFFECTIVE
Use effective when you want to say that something gives the result that was intended. Effective tells us whether something has been done, not how it was done. The focus is on the result.

Being effective can also mean officially start.

EFFICIENT
Use efficient to say that somebody or something works well without wasting time, money or energy. Efficient tells us how something was achieved. The focus is on the process, on minimising cost or waste.
We are installing a much more efficient cooling system.

To sum up, effective is goal-oriented and focuses on the ability to produce a wanted result; efficient focuses on how little was wasted to produce the result. Or, to quote Peter Drucker, being effective means doing the right things, being efficient means doing things right.
