Efficiency and effectiveness

According to the Oxford languages site (the one Google search uses for definitions), efficient comes from the Latin efficere meaning ‘‘accomplish‘. It is defined as ‘achieving maximum productivity with minimum wasted effort or expense..’

Efficiency is the (often measurable) ability to avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result. In a more general sense, it is the ability to do things well, successfully, and without waste


Oxford languages define effective as ‘successful in producing a desired or intended result.’ It comes from the same Latin word efficere meaning ‘‘accomplish‘. 

Effectiveness is the capability of producing a desired result or the ability to produce desired output. When something is deemed effective, it means it has an intended or expected outcome, or produces a deep, vivid impression.


In a world full of people chasing efficiency, be a person who is effective.
