productivity is the ability
it is the ability to achieve the expected results with the minimum expenditure of resources
If you are referring to the work environment, productivity determines how efficiently a person performs his/her tasks and achieves his/her goals
One way to increase productivity is to plan your time.
You can also read relevant literature to help you structure yourself 
like this one:
Chris Bailey’s idea is that time, energy and attention are strictly interrelated. If you waste time on secondary tasks, it doesn’t matter how much energy you have or how focused you are. You won’t get the major thing done by the end of the workday
If you can’t focus your attention on what you’re doing at any given moment, no matter how much energy you have, you won’t be able to fully realize it at work
And if you can’t manage your energy, it doesn’t matter how attentive and punctual you are - “there’s not enough fuel in the tank to do everything you set out to do”
