What is the different between efficiency and effectively?
Efficiency is getting the job done in as little time with as little cost as possible. Effectively is get the job done with the desired "effect". That is to say, the product or service meets standards, expectations with the desired results at the end. These two terms can be mutually exclusive. In other words, you can be efficient but ineffective or visa versa. It is best for all concerned to strive to be both efficient (getting things done in as short a time and as low cost as possible) and effective (having a customer who is satisfied with the results of your efforts). Both win in this circumstance.
