The concept of productivity can be reduced to this practical rule: the more you can produce (output) in any period of time (input), the more you are worth to your employer.

The answer is: Valuable

Explanation:

Productivity is a measure of efficiency. Efficiency is the ratio between total product output with the total amount of resources consumed to achieve that output.

For example Salesperson 1 (S1) is able to close 10 sales per hour, while Salesperson 2 (S2) can only close 6 sales per hour. That means S1´s productivity per hour is 10 while S2´s productivity per hour is 6.

If you were the sales manager of the store S1 would be a much more valuable employee than S2.
