Productivity can best be described

Productivity is also known as efficiency.

Explanation:

Productivity or efficiency is the ratio of output produced in any process to the input given for the process. The input can be of any form, capital, resources, mental or physical labor. A product is said to be efficient or productive when it produces the maximum output or results, when minimum input is given to complete the process. It is important to be productive in any form of work we do.
